I view the Switch Pro as something that is a cross being a new iteration and a new generation. The graphics leap will be generational but it will share similar architecture with the previous switch so that its easy to make games for both systems and old games automatically work on the new system.

If this was the whole year's lineup that'd be one thing, but it can't be emphasized enough that this is just what we know as of less than two months into the year, in a time when games are often announced at short notice, like Crash 4 which was just announced a month out.
Heck, it's possible by the end of the year we may get the new Resident Evil game leaked by the same insider who leaked MH Rise, which he says is similar in budget to RE8.

Oh the next dragon quest is coming to switch all right, DQ's main market has always been japan.

They aren't anytime soon, but there are a few people that act like it needs to happen for major 3rd party game.  This is of course in spite of the fact that the Switch has proven that Nintendo found support without those games anyway, so it is a non factor.

Thats why I myself slate it for 2023-24, because that would be a solid 6-7 years on the market before getting a full successor.  The closer we get to that however, the less likely I see a substantial "pro" upgrade happening as it would be phased out too soon.  Unless it comes this year, the best I can see are smaller upgrades rather than a jump like the PS4 Pro and One X were.

Agreed. If ahave a game company, I will wait for Sony/Microsoft to grow in userbase and launch my games on PS4/XBOXone/Switch/Pc. 

The Microsoft and sony new-gen only in 2023. 

I feel like it is still a bad idea and waste resources on porting games for a smaller audience. I would like to be proven wrong if they do decide to make it real. I feel like games like Cyberpunk, MH World, Assassins Creed, and other big 3rd party games that was playable on the PS4 and XB1 will be more suitable to port it for the Switch 2 at its launch year than the Switch Pro. 

Anyone's individualistic views are pretty irrelevant to what Nintendo will or will not do.

Nintendo have always done "their own thing" irrespective of the market or the consumer.

Keep in mind that games on the Switch are already designed with higher resolutions/graphics and sometimes framerates thanks to the docked mode, which doesn't get used in handheld mode, that is something that can be taken advantage of in the future. - Will Nintendo do it? Who knows.

Agree with you there. Switch will continue to sell well, due to some excellent 1st party titles. The odd 3rd party game like Witcher 3,Doom and Hellblade are always welcome.

The main thing people forget with this topic is that games actually take time to make.  The second that Switch became successful, there was not going to be a huge outpouring of games.  It takes time to properly make a game.

The other thing though, is the timing.  I got this really wrong.  I thought games from handheld series like Bravely Default 2, Rune Factory 5 and Monster Hunter Rise would be on Switch by the end of 2019, but we are only getting them right now.  Here is what I think actually happened:

1. Third parties were unsure about the Switch as a concept before it launched.  "Would it sell more like the Wii U or 3DS?"  That would have been their thinking.  So they waited until after launch to begin development on games that would normally just be the next game in a handheld series like Bravely Default 2.  Remember though that in 2017, it looked like Switch would sell about the same as the 3DS.  That is all they needed to start development on a game like BD2.  These third party games we are getting right now are based on the belief that Switch will sell like the 3DS. 

2.  Development on a brand new Japanese 3rd party title for Switch that is traditionally handheld is about 4 years.  We are just now getting the games that were approved based on sales data from 2017.  Why did it take so long?  Part of the delay is due to COVID.  But I think a bigger part is that handheld developers tend to be smaller.  The power leap going from 3DS to Switch was a lot bigger than the power leap from DS to 3DS.  That has slowed down development a lot.  Either the game will take a long time or it will be rushed and incomplete like Sword/Shield.  That also meant that up until now, 3rd party games were mostly indies and ports, because these games don't take nearly as long to develop.

These games were always on the way though.  The 3DS had plenty of third party exclusives.  Why wouldn't the Switch?

What really blows my mind is that all of these games are based on the belief that Switch will sell like the 3DS.  Last year it became obvious that Switch will actually be Nintendo's #1 or #2 best selling system of all time, totally blowing the 3DS away.  Just imagine how many third party games got green lit for the Switch last year.  The DS had a significantly bigger game library than either the GBA or 3DS, simply because it had a bigger install base.  I'm pretty sure that the 3rd party support Nintendo will get in 2024 will totally put this year's offering to shame, even though this year's third party support puts every previous year to shame.  There are going to be a ton of third party games set for a 2024 release, although some of these might be delayed for Switch 2 or maybe have a cross-gen release.

Im not basing this based on views..  Im basing it on the leaks on Resetera from validated insiders as well as the Nintendo President's recent comments about how times have changed and they no longer view things in terms of fun not being associated with powerful hardware.
