I think he has a lost to answer for with the Wii and the the upcoming U Since last year they admit they did a poor job at the Expo.
LOL all he needs to do is show new Mario, new Zelda, probably a new Mega Man, etc to make that crowd a bunch of drooling Pavlovians.
The fact that a year went by with no Wii U yet will certainly be something he better address to the crowd with release date and price info.
But the real factor is both Microsoft and Sony have to actually wow the crowds this year as well. Microsoft was HORRIBLE last year.
