Hmm. I don't think they could call 2D Metroid on WiiU viable. I don't think they'd feel they can charge $50+ for it, and I'd probably agree. But I would eat up a 2D HD Metroid with good art that built upon the groundwork Super Metroid laid. I suppose that would be viable for them on 3DS and I'd take it there too.
3D Metroid I'd only like to see on WiiU, so you're right that would be a mistake.
I could go for a new and improved version of Battalion Wars (modern console Advance Wars branch) on WiiU, but it wouldn't be a success. They could hopefully push a million units with a fantastic Advance Wars on 3DS.
F-Zero I'd take on 3DS any day! But I suppose the WiiU would need it more, and of course HD would be impressive.
I think the Miyamoto IP of course needs to be on WiiU. But sadly I think no matter the quality it will probably be no more successful than his last big IP Pikmin on the system. I hope it makes money and isn't something Nintendo will abandon. They can use new IP, we all know.
Fire Emblem I don't know. It's a type of game that wouldn't really benefit from being on WiiU, and as niche as it is it probably wouldn't sell well there, half a million. They have the chance to grow it again with another million seller if they make the next portable entry new and tempting enough.
And Star Fox needs WiiU, and it needs to be nothing like Star Fox Adventures. But I just don't know how relevant Nintendo can make an arcadey space shooter like that in the modern age. It was great for the market 15 years ago but Nintendo will really have to work on revamping it and bringing something new but still having it be the type of game we want.
Star Fox, F-Zero, and Fire Emblem aren't the things that will hit big for them, though, anywhere. Metroid probably moreso, but it'll be no Mario or Zelda for them in terms of pure volume.
Knowing Nintendo I can see them making maybe one of these "mistakes".
