So Nintendo will announce their true next-gen? :O
BTW, it's not "ditching" Wii U really. This new thing won't probably come out till late 2015. So we're still getting most important titles for Wii U.
Revealing a new console 18 months before launch? That would kill WiiU sales completely. Why risk the sales of those on the fence waiting for MK8 or SMB to buy one?
You don't need to reveal a console so soon nowadays.
