I'm trying to get a screen cap, but can't seem to get MPC to work. If anyone wants to do it, it's at about 36 minutes into the conference, when the ATI and IBM logos are displayed...
or maybe this means GC controller will work on Rev and we don't have to buy more for multiplayer again, makes sense since Rev controllers will be wireless.
I kept wondering where the hell they were hiding the controller and/or ports, but then again that was just a prototype device Nintendo was showing off.
