Probably not until December. All of their games for the year have been announced, they've done all they can. It's up to customers now to either buy them or not buy them.
November 22nd is make or break. Mario 3D World, Zelda, and Mario Party all on the same day. If that doesn't jump-start and spur sales of Wii U and 3DS to at least meet expectations, then I don't see how the business model makes sense anymore.
