I didn't watch them as I have been dead in the water, but I have heard a few things on the next Playstation.
I heard around 500 gig memory and bigger and a few other things I can't remember. But, I heard they may start to drop disc based games and go for purely downloaded games, although I think this won't happen for a long while, most of us aren't ready I think.
As for the new Wii, I think after the gamecube Nintendo has fallen from my favor. While motion control is cool and all, it has its limits. I would rather sit down and be lazy rather than stand and bust a move. The new Wii with the touch screen controller is kinda neat, but unless they have some magic no slip screen I think that it will be a flop. Even a little water on a iPhone screen makes it almost useless, (To control not stopping it entirely).
