Nintendo should heavily invest in Sony and go Playstation only. Nintendo sometimes makes great games but the hardware design is horrible and only got worse after the weak SNES CPU selection.

It at least rules out the possibilty of about one 3rd owning PS/XB consoles. Furthermore, all you have to do is look at the demographics of the systems. The bestselling games on PS/XB are nothing alike the bestselling games on 3DS. Sure, I can't with 100% certainty confirm that most 3DS owners don't own a PS/XB system, because I don't have the resources to conduct market research like that (Nintendo has though...), but I can say that it's a lot more likely that a vast majority of 3DS owners don't own PS/XB than it is that a lot of 3DS owners do own PS/XB.

Once again, we don't know with 100% certainty whether their hypothetical handheld projects would actually sell massive numbers. However the likelihood that they will is pretty small, while the likelihood that core franchises like Mario Kart, Smash Bros etc. would see great success as home console multiplats is much much higher.

Yes, they would get a bigger library for their handheld by not developing any home console multiplats (though as I said, their handhelds would already get substantially more support than today), but that doesn't mean that their hardware would suddenly sell a lot better. They'd risk cannibalizing their own sales because they'd be releasing quite a lot of games, and they'd see their own softare competing with itself, eating potential sales from one another, instead of release a bit fewer games on handheld, instead releasing them on home console, where they most likely would sell substantially more than what those teams' handheld games would.

No. Why would I? Are we so attached to names, brands and faces?

Their only home-console franchises I care about are Pikmin and Paper Mario. It is not worth paying the price for their consoles for me, so yes, I'd prefer them to simply sell their games on Steam or Playstation.

It honestly depends on what the next console is. If it's like the GC and is just a normal, powerful console, they might as well go 3rd party because it won't be much different than the PS/XB anyway.

If they make another Wii U, I'd want them to go 3rd party because it would be a less powerful console with a bad "gimmick" attached.

However, if it's like the Wii & actually does what I consider a good "gimmick" then they should stay in the hardware business.

In all honesty tho, I'd be happy either way as long as the quality didn't go down with their games

Except for Nintendo UI that's all possible on PC with an Xone controller 

Nope wouldn't care, I am not a fan of the Nintendo phylosophie on console gaming. Neither do I see the 3DS or Wii U as innovative forces that made the industry move forward. You know who did MS with online gaming and Steam for allowing Indies. Sony pretty much did what it always does since the PS2, (provisie a variety of games and take doftware risks once in a while) although the PS+ idea and PSVR are nice. Just because something is different that doesn't mean it's innovative since the idea also needs to be wanted. The Gamepad and 3d screen in 3DS where not wanted but just kind a there and that is how they are treated. Well perhaps the NX does something different that we gamers want but if that's not the case and the NX will be a slightly more powerful PS4 with a gimmick that won't be very useful I would rather see them focussing on third party.

Yes, i only love Zelda, the other IP's are not may taste at all. There is no logical reasoning from people who do not want them to, people who buy there consoles still get the games.

I would mind a lot. This would spell death for handheld gaming. If they just put smash and mario party on other consoles, it's okay.

I don't mind. But I say I don't think I'd care enough to buy it full price.
