I was about to create this thread :P
I think it was a good conference, as it was pretty much non-stop all the way through, never got bored, except for Kinect Sesame Street and Disneyland
but I think it was a bad conference for announcements, bare Halo 4 (WHICH I LOVED), there was no other announcements at all (ok Minecraft, but PC ftw :P)
so 4/10
EDIT
someone voted 10/10, they must really love Halo :P
