What are your expectations of Microsoft this E3?

I just want to see Halo 4 single player gameplay. It's the only game I am really excited about, but I don't care about multiplayer like so many other Halo fans. I'm all about the campaign. After E3 I plan to replay all the Halo games again leading up to Halo 4. The Chief is back!
