Nintendo is fine. The 3DS has sold 30+ million units, and most of the top sellers for it are Nintendo-developed titles. The Wii U is backwards compatible with the Wii, which means gamers who skipped out on the Wii can catch up on two generations of Nintendo classics in one console. Megaman is going to be in SSB, which is going to make it a must-buy for some people. And it's probably going to have sub-$250 bundles for Black Friday.
I'm guessing the Wii U outsells the other two consoles this generation.
It can't run Gamecube games.
Well aside from Genogears 2 and Bayonetta 2 coming in 2014... there's nothing to hype for the WII U.
New Smash, Wonderful 101.
...Other than that, you are right. On the other hand, online Monster HUnter 3.
