Eh, I don't really care who does the "best," I'm impressed by, well, whatever impresses me.
I expect E3 to do what it's always done for me: Show me more of the games I'm already excited for and REALLY excite me with a surprise announcement that I never saw coming. It's a pretty vague expectation, I know, but it's never failed me, and I LOVE that surprise announcement. Last year it was Gears Of War: Judgement, the year before it was Halo 4. I don't remember the years before but it never fails.
However, without G4 to bring me everything in a nice orderly manner, I don't know where I should get my E3 feed now.
