I really am starting to wonder if some games may be made available for the Wii U and also the Nintendo Fusion/4DS (whatever it's called) in 2016.
The architectures should be similar as Iwata has said he wanted future platforms to "absorb" the Wii U architecture, that likely means a similar GPU design philosophy from AMD, just one based on mobile computing, in the same way the Tegra K1 is a Kepler based GPU for tablets/phones.
Maybe some games could be shared by the two platforms before Nintendo fully embraces Fusion (home and portable) as their future.
That might be why they're so hush on SMT x Fire Emblem, lets face it, that game probably would sell a lot more as a portable game, especially in Japan. But they already promised it for Wii U too. So if its easy to port it, why not make it for both systems?
Things like Hyrule Warriors 2 and perhaps Luigi's Mansion 3 might also fit into the same mold. It would help these games sell better, fill out the 4DS/Fusion launch which is make or break for Nintendo's future, while still giving Wii U owners who don't have the portable more games to play.
