Earlier on G4, the E3 coverage team (i.e. every on-screen personality on the channel), asked who won E3. My instant reaction (and poll-winner) was Microsoft. They did debut Netflix (which I was looking forward to on PS3), announced Final Fantasy XIII will be on Xbox (if anything), and showed off their avatars.
But to say that Microsoft was "Best in Show" was highly misleading. Neither Microsoft, Nintendo, nor Sony showed us anything worthy of the adverb big. There were lots of news, tons of footage of upcoming games, and cool new things revealed. I feel like third-party developers were the real winners this week. Exclusive titles are becoming less important, and more big titles are making jumps (FF13, Bioshock, etc.). This can only be good for fans.
Best of E3*
Resistance 2 (gameplay footage)
