I hope these 3rd party games aren`t just games for the japanese launch. For example, a Black Ops 2 announcement is needed!

BOII would be a nice thing to show off Nintendo's new Online structure. It could also take in more sales. 

Not sure if it's needed though.

BO2 is known for it`s multiplayer - that people seem to play forever - and the fact that, according to some, it also attracts the more casual gamers.
So, having BO2, more than any other game, will only benefit Wii U in online play and sales!
