Well, I personally give that conference an A-...it was presented nearly perfectly with a nonstop barrage of games. The problems were that far too many games showed CG instead of gameplay, which is fine, but it certainly holds back excitement. Also, while there were a few big new games, I don't know if there was really a Megaton...
I am quite impressed with how MS handled their show and I hope the rest of the conferences keep it up. This could be a great year for gamers!
