EA's press conference was definitely better than Microsoft's conference. I found MS conference actually a bit boring. Even though the Kinect as a technology is impressive and interesting, the presentation of it was not.
I also thought Nintendo's conference would be more of a catering to Nintendo's biggest audience, the casual gamers. But I was very wrong.
Is still want to see Sony's press conference and the Kinect press conference, but they seem no longer available on Gametrailers. At least I don't seem to be able to find it.
Fun fact: IGN is having an open poll about which of the big three was the best at the E3. Nintendo is leading, with Sony close behind and both of them leave Microsoft far in the dust.
