-bayonetta 1 announced for wii u, and will be a free download to anyone who buys bayonetta 2 from the eshop.
-sonic and mario platformer announced as the third sonic game for wii u
-persona 5 wii u exclusive. more details from atlus on november 24
3ds:
-miiverse support, and integration with the new account system
-super mario galaxy 3d announced for 3ds
-majora's mask 3d announced for 3ds
-persona 4 the platinum announced for 3ds: includes everything from golden and extra stuff
