X I guess? Apart from that, nothing really... Unless they really want SSB for wiiU

Any game that they would care about that will come to WiiU wont matter all that much. Most 1st party WiiU games have counterparts that already released on the 3DS and the 3DS is always going to be more popular as it also gets major 3rd party games and well its a handheld.
Nintendo competes with themselves and their home console will struggle because of it.

For home consoles they might have liked yakuza, persona or dragon quest games. But they are not in Wii U (except yakuza 1 & 2 HD). So Wii U is not that much attractive to them.

Basically what they need is what Playstation usually gets, FF, RE, KH, Tales, Yakuza, Musou, SF, Gundam etc etc. And they need them exclusively like what PS technically has in Japan.

What we are seeing is that 3ds games are coming to wii u (some of them). And we know how big handhelds are in Japan.

But i do want anime games to come on the wii u, not just psvita and 3ds, but it goes back to that reason.

Yeah. Plus these games are actually loved by Japanese home console gamers. But for some reason Nintendo isnt taking any initiative to get these games in Wii U.

The only game that even remotely matters for Japan anymore on the WII U is SMTxFE and the status for that game is uncertain at this point since Sega just bought Atlus.

Xenoblade Chronicles didn't do so stellar in Japan and the last zelda on the WII bombed in Japan ...

I really disliked Skyward Sword. Limited corridor area was nothing like big open world OOT / TP had. Plus I really hated the controller options.

Top PS3 game last generation in Japan was FF13 with 1.87 mln. Next was RE5 with 1.08 mln. Next is FF13-2 with 0.89 mln.

Top WiiU game currently in Japan is NSMBU with 1.21 mln. Wii Party U is 0.79 mln. MarioKart8 is 0.68 mln there. I'm totally sure that LT sales of MK8, WiiPartyU and Smash WiiU will be higher then 1 million in Japan.

So how can you say that WiiU games are no matter to Japanese if they still sell better than the best selling PS3 games last generation?

Your not alone on that ...
