I'm willing to bet the only ones that will be availible during it's launch are:
Batman: Gotham City
Rayman: Raving Rabbids Wii U
Lego City Stories
That Marvel Pinball game
Hasbro Family Game Night 2
and of course: more crappy kid/dancing/nutchuck shaking games.
I don't think we'll be getting hot titles like Pikmin III, Darksiders, Alien: Marine Hunters, and etc. unitll much later on, unless things change.
What do you think will be available?
