The 3DS has a lot of support from third parties, but of course they are not making Assassin's Creed games, nor Call of Duty. They are making games to take advantage of 3DS specs and features, and Nintendo is not trying to cram a full Call of Duty on the 3DS. The problem is, Nintendo will want to cram a Call of Duty on the Switch, even if it looks like a PS2 game. That is a huge mistake. Nintendo should focus on games that are possible on the Switch and will benefit from it. Just look at Dragon Quest XI! The game on the Switch NEEDS to be a 3DS port and NOT the PS4 port. The Switch will benefit much more from a 3DS port that looks so much better, than a PS4 port that looks so much worse. Also, people may want to double dip and buy both versions, since even though they are the same game, they are different experiences. If the Switch gets a PS4 port, people that want the game, may prefer the PS4 version, since it looks better, and won't compromise performance and/or features.

Well like I stated before, that up to 3rd party, not Nintendo. If Nintendo feels the power of the Switch makes sense for them, how 3rd party approach it is their business.

This is where I side with Nintendo. Its their platform, they made it to max out their content.
Look at Breath Of The Wild.

In my opinion, that is good enough for them, legit for 5 plus years.

So Nintendo is focusing on games that are possible on the Switch, they are not Activision.

"The game on the Switch NEEDS to be a 3DS port and NOT the PS4 port"

Well sure, but that is up to Square, not Nintendo.

In Nintendo's defense, they don't control what those 3rd party put on their system that much, its still up to Square, Activision etc. I don't think Nintendo wants 3rd party support from those AAA, I think they are ok with it, but they expect support like they saw from 3DS, DS etc.

I think its a good choice to be honest.

The versions that other publishers choose just isn't Nintendo's issue. I think they are fine knowing they have a lessor system in terms of specs, but a portable in terms of more market control. I think its a respectable trade off. Look at 3DS, 70 million units is still money, didn't need to be the power of the PS3 to get that. Switch will be fine. Need not worry about other publishers porting titles. That really isn't up to Nintendo.

"Stuff like a new Tales Of title, Dragon Quest, Monster Hunter, or a new Mana title, or BG&E2, amongst many other possibilities."
Yeah, that´s the stuff I want for the Switch, and for it to have the variety the 3DS has. That's the best way to go for the Switch. It's just that Nintendo might be so focused on it to be a home console, that might do deals with third parties that won't benefit the console at all. Nintendo will obvously make great games, but it needs third party games too, and I hope they'll be more like the games for 3DS, than the games for PS4.

My job never flops ;)
nintendo after switch, however, yes
