Aaaand, we were wrong. (OP may want to update first post)
Tomorrow at 6am PT, 9am ET and 2pm GMT
My predictions are:
New Nintendo 3DS info for west. Price will be significantly lower than I've just paid for my ambassador, and the release date will be sooner than I'd want it to be. (Grrr.)
Xenoblade 3DS, Majoras Mask and Codename STEAM release dates, and why they're much better on New 3DS
Yarn Yoshi and Kirby information and dates
Mario Kart 8 DLC info, Mewtwo release date for Smash
Shibata-san singing karaoke (EU only)
EITHER Star Fox 'announce' trailer, Zelda dungeon footage, or info on SMTxFE
Hopefully something Splatoon related (demo/open beta, something along those lines)
