They will just show it off because it's on 360. Well, there's a chance

Last E3 they had Tomb Raider, a square enix game. There is a chance they might do the same again.

Want I really want to see which hasn't been announced is a chunk of time dedicated to XBLA. MS has been of fire with it as of late and I'd like to see what they have planned. Twisted Pixel announced that they'll have a reveal at E3 so that wish of mine looks like it'll be coming true. Alan Wake 2 would make for a nice announcement, maybe Crackdown 3.

I'm not expecting much, but Microsoft's E3's always have well presented demos of multiplatform games which I find very entertaining.

Unlike most on this site I appreciate some of the Kinect games already out and I hope to see more of Steel Battalion and hopefully some other core game enhanced by Kinect. I also like everything they put on the dashboard I want them to talk about skype integration. Since most of the games I play are multiplat I don't really care if they don't have a thousand exclusives to show as I wouldn't buy most of them anyway, 2-3 is well enough and Halo 4 and the new Forza game will fullfill my collection at the end of the year.

I hope they don't talk too much about the nextbox if they're not going to release it this year. Maybe they can show a glimpse of what their new studios have been up to.

Huge focus on entertainment/apps and Kinect.
A Halo 4 and Black Ops 2 stage demo.

That's it.

I read the first page of posts and of course this has already de-evolved into a simple MS bash fest........

that being said obviously COD BO2 and Halo 4 will be shown as well as a bunch of Xbox Live and Kinect stuff.

But I honestly expect MS to announce at least 2 major exclusives, whether they're 1st party, 3rd party, or next - gen games.

I think they should have a pretty solid E3.

What the past two Microsoft press conferences have taught me: Don't go in with expectations. 

Alot of stuff with the dash board
halo 4
forza
fable the jounrey
COD
more kinect games, including that crytec kinect game

1 or 2 more multiplat games

MAYBE some kind of exclusive dlc deal with GTA V (either MS or Sony will have somekind of deal)

PRICE CUT

that's about it

#1 Windows 8/Xbox 360 integration. My guess is that Microsoft will have more to show than the Consumer Preview allows currently.
#2 Halo 4 will be a big showcase feature.
#3 I expect to hear about new features to Xbox LIVE. Mainly the new music service.
#4 More games, though nothing I'm really too interested in, but we'll see.
#5 Price cut.
