Even if the game is an atrocity, the Wii U keeps on not getting games, and this one's even worse as it was an already announced game.
This alongside with Rayman, were both among the strong points of Nintendo's E3 show last year, but they both turned into disasters. Most of Nintendo's E3 was smoke. No Aliens, no Rayman, where's Ghost Recon? Nintendo needs to get their act together, people will no longer trust a company with such badly handled console launches and plans. Apologies are not enough, even if it's the 3rd parties fault, it's their fault too, because they were hyping up things that never came to be and they didn't have more content in case something went wrong. Luckily I still don't own a WiiU, but I would be very pissed if I bought a console for games that were vaporware.
A lot of stuff from E3's end up being vapor, or horribly, horribly delayed, or just junk not worth mentioning the first time. Assassin's Creed 3DS? Agent? The Last Guardian? Joyride? Milo?
