When they're positioned to talk about Super Smash, Mario Kart, 3D Mario, Project X, Dream Team, New Super Luigi, Wonderful 101 and Pikmin 3 within one hour, it doesn't leave a ton of time for a bunch of surprises. That's assuming they'll ignore impending 3DS stuff, too, which I'm sure they won't. I wonder if they're saving Wii U news for beyond E3? Because at this point...good lord, Nintendo, please don't.
I'm more scared that they'll fuck it up than I am excited about the potential announcements. Of course, I felt that way during the back half of the Wii's lifespan, too. If they wanna go ahead and re-enact the 2010 conference for Wii U, I'm totally cool with being worried over nothing.
