The conference format was really good. It looks like they had a lot of fun making it and the robot chicken segments were great, they were not afraid of making fun of themselves.
However, even though pretty much everything shown was exclusive, the game line up was fairly meh. No megatons (much like Sony and MS) and the lack of 3rd party cripples their variety, in my honest opinion. Also, it felt sooooo short.
6/10 from me. Best presentation of the three, hands down but the least exciting line up.
