Nintendo and Ubi makes Wii U trailers with Rayman, showing the strengths of the console as well as showing their awesome game. Wii U users hype it up, are bummed that it didn't end up a launch title.
But now it comes! Oh, no it won't... delayed again. "thanks ninty for the publicity using our game in your adverts!".
Oh well... Something else that I also thought of: The Demo. They released the Demo near launch, and now making the users who were able to play it wait a long time. The hype for the game will have cooled off by then. Hell, even more interesting games would've probably been released by then, making Rayman feel "old" as the developers experience evolves rapidly this early in a console's life...
Sure they will sell a lot of copies of this game for the PS360... but it feels like many Wii U users will boycott this now that it is released. I think they would've sold more by releasing the game NOW, for the Wii U, and working in the port just like they are now.
Just like Resident Evil Revelations. Like Resident Evil 4 (it was ported to the PS2 later, right?). Like Bioshock. bah, like every game ever ported at a later date.
