How important is Bayonetta 2 for WiiU's potential for future 3rd party game development?

[VGKing]

The multiplatform Bayonetta was a flop, what makes you think the Wii U exclusive Bayonetta 2 will have better luck?

I don't think that means "a nail in the coffin" for future 3rd party support though. The Wii U's specs and Nintendo being Nintendo decided this way before launch.
