Nintendo confirmed today that Bayonetta 2 as well as the port of the original Bayonetta will indeed run at a crisp 60fps on the Wii U hardware.
They went on to talk about more functionality that these games will have. The optional touch controls for Bayonetta 2 will be in the included original game as well and both games will indeed feature off TV gameplay if you want to chill in your bed with the gamepad.
Both games will also feature options for Japanese and English dialogue. Seems like they are going all out with this release.
