Well like I said, I like that Nintendo offers something different. I have a PS4 and Xbox One, so the Switch getting third party ports does nothing for me. 

To answer your question, the majority of developers do not use motion controls on either of those platforms. They did on the Wii, and I think the form factor on the Switch is more welcoming to motion controls. I don't really like using the gamepad as a motion controller, not nearly as nature as using the Wiimote was. Joycons are the evolution of the Wiimote. 

And before I go for the night, I just wanna say that Nintendo offers a nicer user experience in my opinion than Microsoft does. I really can't stand the updates and installs and UI lag on Xbox One. I don't think Nintendo should drop out to jump ship to that platform. Sometimes, specs in reality are different than on paper. For example, my 32 gigs of space on Wii U went much further than my 500 gigs on Xbox One, which can be used up with forced installs and 40+ gig game updates.

Nintendo certainly offers a different experience there. It's a give or take deal, but having the options is best.

I was watching some footage of "Arms" earlier today and the Joycons do look like they work killer for that game. I am not usually a huge fan of motion controls, but the idea that its totally optional (something that wasn't the case for many Wii games) and simply conveniently the control pieces regularly connected to the normal main controller make it more convenient and handy to try. With a Wii Mote it was like "herre you go, you have to use this". with the Joycons they look intuitive in the hands and and are just detachable pieces that look to function well as just part of the normal assembled controller AND potentially on their own for optional types of games

40 GB updates? that's insane. I agree 100%. The more unique people in the hardware game the better. It would be like if either Apple or Samsung dropped out of the mobile market, that would be a big loss. competition usually boosts innovation and quality 

There's already articles stating "no discernable difference" between the WiiU and Switch Zelda, but I digress, since it is in fact a port. However, for a port, it runs at 900p max. How will it go when some serious power is being requested of it? 

You know what bugs me? Playing outside under a tree for 2.5 hours on an adventure game (made to draw out lots of time) before having to rush in to plug it in again. I'm glad somebody brought up the Vita, because that proves that the Switch will not get any console AAA titles. The Vita proved that people wanted games on portables tailored for portables (stop and go action). Mixing the two in one market isn't exactly what's called an effective marketing strategy. If anything, playing a game from say, a portable front when it's designed more for a home front would just alienate parts of the userbase.

If you've ever worked in any office, the idea of "docking" is not new at all. I actually dock my gaming PC between my friends and my place frequently, AND play it on the go with 5 hours battery. Can it be more seamless? Of course! Are people willing to care about seamless docking, given the premium price, and incentiveof something less portable but more powerful? 

Keep in mind how many LESS people would have bought the 3DS if it remained at its original price. If Nintendo don't sell slightly more than the 3DS base, it should be considered a failure. Why? Because they've sacrificed one of their markets for nothing.

Switch's fate is predetermined. Look at the console cycle for the past... well probably since N64? We'll get a couple launch games, a mario game, and a Zelda game towards the end of its life. In between the B teams will make 1 game maybe 2 during this cycle. After year 3 active development for the machiine will end and all resources will be dedicated to the next machine. Years 4 and 5 of Switch will be a barren wasteland. Its pretty much been this cycle since N64. Even Wii their most successful home console was abandoned early.

Hard to say its not predetermined since they have followed the same cycle since the 90s.

Na, Sony will go third party in the long run. They are already preparing for this with shutting down their studios.

I 100% believe Nintendo needs to go 3rd party. They are leaving 10's of millions of sales of Mario, Mario Kart, Smash Brothers, and many other titles on the table, because they are locked to high priced devices with very small userbases. Releasing Nintendo games on PS4 and XBO would massivly increase the sales of all of their titles, and make revenues and profits explode. They would be looking at Wii level sales of all of their big franchises all the time.

Which is why 3rd parties will shun it, unless it has the userbase. You mentioned development costs before, but what you're also missing is risk. Companies see that a device with a marketshare under 20% is too risky, because it would require a higher % of that userbase to buy the game, not to mention that they're in direct competition with Nintendo themselves for consumers' limited spending money. The Switch's portability will mean diddly squat if it doesn't get the 3rd party support. It will just end up being longer range WiiU.

You realise that several phones have Tegra chips in them, right? That's just nVidia's offering, too. They're no slouches when it comes to decent 3D, and people might see that as an advantage over a $470 dedicated device that might be a little bit more powerful, not to mention having to cart it around and charge it along with their phone.

The problem with the Wii U wasn't to have a tablet in your hand (off-TV play was a great feature), but the problems were that you did not know how a game would use a controller. It wasn't uncommon at all for you to have to use BOTH of the screens at the same time while playing, making the off-TV feature by itself useless. This is why Nintendo avertising for Switch emphases that when you take the tablet out of the dock, the TV is no longer in use. But yeah, the problems with gamepad were just problems with software in the end (just like all the other problems Nintendo have had lately).
