I've watched many press conferences over the past few years and this year was by far the most entertaining. I'm not going to confuse my personal expectations (games I wanted to see, megatons I expected to happen, and disappointment over CGI instead of in-game footage) with an actually enjoyable conference. It's everything you'd want in a conference. I was never bored. I enjoyed watching what they had to show and that's how a conference should be. It's not Microsoft's fault that several of their big reveals were already leaked beforehand. For all general purposes, I'm guessing that the media went away pretty happy.
Sony had a good conference too, but listening to someone talk for 15 to 20 minutes was absolutely boring. You can argue Sony had better exclusives and more games, or whatever, but the conference hit a wall there for a little bit in terms of entertainment. 2 hours is just too much.
