there's that new wii minigame collection thing, right? They'll spend a disproportionate amount of time detailing that and the Vitality Sensor. Then Miyamoto will run out on stage and yell "Zelda Wii! Mario Galaxy 3!! Metroid Prime 4!! Pikmin 3!!" then run off the stage and the fanboys will cream their pants.
Either that or there'll be no vitality sensor because it was all a trick to get other companies to come up with shitty software for a shitty idea for a peripheral.
