I have finished watching all three conferences now and I thought Sony's was the best. Best in presentation and best in all round content. No big announcements, but what Sony needs is games.
Nintendo's conference left a lot to be desired. That woman (whoever she was) on-stage to me felt as if she was addressing some parents PTA meeting, not the specialist press and other people from the industry. Her presentation style felt very clicky and wooden.
The Wii music game looks as if it will sell very well, but the Drum section that was played didn't sound good at all. And that surprises me because Nintendo has always had such a high quality bar.
As always The 1Up Show had some nail on the head observations, but to sum it up, all the conferences where lacking in one way or another.
