Miyamoto will come on stage, and say, "FUCK YOU core fans, now we're catering to the soccer moms."
In all seriousness though, I think we're going to see a new peripheral that will hopefully give the Wii a bit of a shot in the arm. Maybe a do-over of the Nunchuck (the motion sensors on it aren't really good. Makes sense to use it for 1:1 motion control. That'd be great for future FPS games too. Dual wielding, anyone?

)
Nintendo will add Gameboy titles to the DSi Store. Makes sense considering there is no slot on the DSi. And hopefully, they'll announce Pikmin 3. Miyamoto said that last year, and I remember there was a teaser of it in a magazine I read. If Pikmin 1 enhanced for the Wii says anything.
I know this is a pipe-dream like nothing else, but I REALLY want to see if there's going to be a new Viewtiful Joe for the Wii. But it seems extremely unlikely.
If any of those wishes are fulfilled, I will stop pirating games (virtual console included) for the Wii. Cross my heart.
