It seems that there´s a lot of misunderstanding here.
Isn´t Ultra Street Fighter IV dlc content ? For the suggested price, we can be sure that it´s not a complete game. It´s more or like what Nintendo did with Super Luigi U, and add-on to a already launched game.
If this is true, then there´s no real motive for so much fuzz. SFIV was only launched with dlc support for Xbox360, PS3 and PC. There´s the 3DS (more than 1 million pieces sold, by the way) but it doesn´t support dlc.
Now, it seems that Capcom is planning to release another version of this game in a complete package. It doesn´t make much commercial sense to launch it, but still it will be only for the original platforms. No PS4 and Xbox1 included, so.... anyone would suppose it wouldn´t be on WiiU also, after all, we can say that it´s an old game now.
Considering the efforts Capcom did with Resident Evil Revelations, Monster Hunter 3 Ultimate and the upcoming exclusive (and BIG) Monster Hunter 4, as well as the all the classic Mega Man games lauched on Eshop, we hardly have reasons to argue about Capcom´s support to the WiiU
