Sony, the rest of the conferences were pretty MEH. Anyway I'm more interested in the things that weren't announced in the conference, but will be presented at E3.

well Sony did show off about 20 new games (like my sources told me)

I think Sony won. Microsoft dropped of course the biggest bomb, but it was after more than an hour of an increidibly boring conference. Sony didn't drop a bomb as big, but they had a particulary interesting show, with great games. Nintendo, of course, last place

Sony. They didn't sell out or resort to stealing exclusives to win.

Sony, because im a shooter fan =)

IMO Microsoft. Sony showed the most games and Nintendo proved that they are milking the casuals market dry while just barley paying attention to the hardcore, but I think Microsoft had the biggest surprise and is in the best long term position. PS3 lineup is far too shooter heavy, and Xbox already owns that market.
