I know Sony hasn't gone yet, but I think Nintendo will end up with the best conference of E3 2010. NBA Jam is returning, hopefully the controls are fluid, along with a re release of 007 GoldenEye. Those right there have me sold, but you thing about all the core franchises returning and Nintendo is doing what there fans want. Yeah, there isn't a new IP other then Epic Mickey, but so what? There was only one of those cheap Mii style games (Mario Party: Mii edition).
 
Now the 3D stuff is crap in my opinion, but we all said that about the motion controls and that is the big thing. So I guess I'll have to wait and see for myself, though it will be tough as I'm not buying one, if it really works out well or not.
