Mario K..Ka... nah that will suck ass.
I dunno, Maybe Animal Crossing 2 will be shown... besides that, there will have to be somthing origanal. Normally the show could be saved by:
1. A Rare Game (impossible now)
2. Zelda (on the brink of release here, already out in Japan)
3. A Mario Game (Maybe?)
4. Announcements of a new prehaprehal (Online gaming maybe?)
5. A new Shiggy game (even though the last few sucked)
6. Pokemon (Isn't there a game coming out soon anyway?)
If we are talking about sequals, they could come with some early shots of a new Nintendo franchise game. This year they simply don't have a game that will blow everybody away that we know of before hand like Halo 2 or MGS3.... they could have a shock game though.
