It's funny you think the infrared pointer is the most defining feature of the Wii remote.  What matters most is how it is used most commonly, especially in the most popular games.  Also, what is the point of this argument?  Do you personally believe that Wii is not an arcade machine now, or are you just nitpicking on stuff that you don't really believe in the first place?

3D is definitely an aspect of PC gaming.  Myst, DOOM, Wing Commander, etc... were all big 3D franchises in the early 90s.  At the same time the arcades had Virtua Fighter and that was about it.  The big 90's arcade games were 2D fighting games.  

The mistake you make is that you think arcade gaming is defined by consoles.  It isn't.  Arcade gaming is defined by the games that were in the arcades.

Once Nintendo was able to get their arcade games directly into people's homes, their arcade division became more about porting Nintendo arcade type games from NES/SNES to coin-op rather than developing them the other way around.  See their VS. and Play Choice 10 coin-ops, Dr. Mario, F-Zero, etc.  Sega was more rooted in developing both coin-ops and home console games.  Sega has actively developed coin-ops from 1966 to today while their home console division came and went in less than 20 years (SG-1000 released in 1983 to the discontinuation of the Dreamcast in 2001).  But, that's not to say they didn't evolve their home console games of the time with the changing hardware.  Sonic 3 didn't have an overworld, but it did have save files.  Outside of platformers and previously mentioned RPG's, Sega developed strategy simulation games like Advanced Daisenryaku: Deutsch Dengeki Sakusen, Super Daisenryaku, The Hybrid Front, Ninja Burai Densetsu, Bahamut Senki, etc. all featuring battery backup saves.  Also, compare a Sega developed sports title like Greatest Heavyweights to an arcade ported boxing game like Punch-Out!!  Greatest Heavyweights featured a Create-a-Fighter, a Career Mode (featuring 30 fighters to box until you win the title followed by 8 title defenses against real life legendary boxers), and a battery back-up.  These are the reasons I wouldn't label the Genesis/Mega Drive as strictly an arcade system.

Here it is.  This sentence from the quote above is the actual core of our argument:

"My stance on this matter is that mouse controls for PC games were something inspired by the simplicity and accessibility of arcade games, therefore any mouse-like controls do not constitute the original PC DNA, but rather are an alternate form of arcade DNA."

When you use the words "arcade" and "PC" that is not actually what you mean.  Instead when you say "arcade" you actually mean "simplicity and accessibility".  When you say PC, you actually mean the opposite, "complexity and inaccessibility".  Your original table is actually a 5-point scale for accessibility.  You would actually make your points a lot more clearly if you relabeled it as a 5-point scale for accessibility.  I actually think if you labeled it that way, then I would agree with almost all of the ways you categorized the consoles.  (We would still disagree about the Switch, but that is besides the point.)  If you are saying that the console market has gotten less accessible over time, then I would agree.  I would also agree that a more accessible console tends to bring in new customers, or at the very least, it prevents repelling customers.

However, I am using the word "arcade" to mean "this actually was in the arcade" and PC means "this actually was on the PC".  If you ask any random person on the street, almost all of them will associate the mouse with the PC and not the arcade.  The mouse was also not inspired by the arcade.  It was developed by Xerox.  It wasn't inspired by arcade gaming, because Xerox isn't even a gaming company, much less an arcade gaming company.  Apple stole the idea from Xerox, and then Microsoft stole the idea from Apple.  The mouse then lead to the mass cultural acceptance of home computers via the Mac and Windows.  The reality is that it doesn't get more PC than the mouse.

In short, your table is confusing.  Just change the labeling to a 5 point accessibility scale and it becomes a lot more clear.

Our views on this are not that different.  Sega definitely made a lot of great games for the home over the years.  However, they never abandoned pure arcade gaming.  The Genesis, especially, was probably when their arcade games were at their peak.  (Not to mention third party arcade games on the Genesis like Mortal Kombat, Street Fighter, etc...).

Nintendo basically did abandon arcade gaming in the middle of the NES/Famicom era.  This was about the time that they developed the Famicom Disk System (FDS), which featured games like Zelda 1 and Metroid 1.  After a while, they stopped supporting the FDS, but it changed their game design philosophy forever.  They stopped making pure arcade games after that.  Even Nintendo made games that could be ported from SNES to an arcade are fairly uncommon.

So, where to place the Genesis?  I put it in a pure arcade column to highlight that it was much more of a pure arcade machine than the SNES was.  If a person in the early 90s wanted a console for arcade gaming I would recommend the Genesis.  I would even recommend the Genesis over the Neo Geo, because Sega made better arcade games than SNK did.  The Atari 2600 didn't only have arcade games, but it has more of an arcade focus than the Genesis.  The NES actually had a lot arcade games, but the most memorable NES games tend to be from Zelda 1 and later rather than before Zelda 1, so it barely makes it into the arcade evolution column.  I'd put the Genesis just slightly more arcade than the NES.  Maybe it belongs in column 1.5 rather than column 1 or column 2?  But I chose column 1, because it's arcade focus is significant compared to the SNES.  In fact, every Sega console has more of an arcade focus compared to its Nintendo counterpart, because Sega never really left the arcades, while Nintendo left the arcades in the middle of the NES era.

This is an interesting way to look at the console market. I really disagree with the Wii U though. It's more in the balance category. The Wii U was a pain in the ass to develop games for (that hurts the PC evolution argument), and had an off-screen tablet included.

What we know is that full body motion control isn't suited to Switch Lite or the hybrid in handheld mode.

Switch hybrid sold 3m in Japan in the same timeframe that RFA sold 1.5m. Either half of those Switch hybrid sales were due to RFA or some/most of the cazulz were already there. We can also safely assume that there are cazulz that aren't interested in RFA.

RFA currently has a 16% attach ratio to the hybrid Switch in Japan despite stock issues, higher price (compared to Wii-Wii Fit) and apparent lack of console accessibility.

ARMS was above 2m and 1,2 Switch was above 3m before RFA released so Nintendo fans have probably spent as much money on 12S and ARMS as they did on Wii Play and Wii Boxing.

Ubisoft didn't bother with Just Dance 2020 on Wii-U but did make it their last game for Wii most likely because it took 10years for a system to come along that could eat into the Wii versions sales.

Switch+RFA was hitting Ebay prices not seen since Wii+Wii Fit during the pre-pandemic holidays.

Seems ludicrous to credit FIFA, Skyrim and Witcher fans when ARMS, 12S, 51CHG and RFA easily outsell them and there are still 130m DS and 75m Wii owners out there who didn't buy Brain Training or Wii Fit.

I'm not saying the uber-cazul Just Dance, Wii Fit, Mario Kart wheel users are responsible for Switch's success just that a significant portion of them are back buying their first system since Wii.
The main driver of Switch sales is the returning Nintendo casual-core/lapsed gamer crowd, some of whom were uber-cazulz during the Wii/DS days but have since crossed the bridge Nintendo built for them.

Wii Play sold 28 million copies.  But I think that even when people mention the fact that it came bundled with a Wiimote, it often gets forgotten that there was a huge Wiimote shortage at the time.  Consequently, a great many people bought Wii Play solely to add an additional Wiimote to their Wii for all the other couch multiplayer games they already had.  I was one of those people.  I remember struggling to find any game stores in my area that had individual Wiimotes in stock at the time, and having to buy Wii Play just to get an additional controller into my living room.  I remember playing through Wii Play with friends just once and then never having the desire to pop it in again.  It did not have the fun and addictive quality of Wii Sports.  I also remember a video game magazine at the time, that covered top selling games of the month in each issue, being very noticeably irked at having to include Wii Play in the Top 10 for as many consecutive weeks as it did.
