No, I really do not expect any new Forza, Halo, or Gears of War game there. That would be a bad move on their part. Besides Gears of War: Judgment is already set to reveal a new trailer there anyway. Fable, maybe, but I still doubt it. What I imagine is it'll just be a lot of Xbox  360/Xbox Live promoting rather than actual big exclusive game announcements for Microsoft, such as a trailer to a new game (multiplat), then flashing the Xbox logo or announcing the infamous exclusive/timed DLC for the game or trailers for DLC for games that are already out such as car packs for Forza or whatever etc. I really don't expect much.

That would probably be the greatest announcement made in years, I hope MS hasn't forgotten about PGR.

Hhhhmmm...I bet a Halo game is talked about but maybe not Halo 5. I'm interested to see what happens with Gears...it's not too early for a Gears 4 launch but there is still always a chance that it goes Bioshock and comes to playstation aswell. Not likely but possible.

Now, I have a feeling a Forza game will be anounced but I don't know if it's what's best for them. They need to be careful not to release them too fast. More than a few people thought that they didn't make big enough strides going from the 3rd to the 4th instalment. I say hold off for a year, make the changes and upgrades and additions that they think the game needs. In the long run I think that would be better off for both the developers and the fans.

Hell no to Gears please don't announce a Gears of War 4. Forza is doubtful since Horizon just came out and Halo 5 is the same reason as Forza. It would be nice to see a new Ip announced maybe even just a trailer of a next gen game.

Hoping for Crackdown 3, expecting some Kinect crap.

What about the rumors of a new Odd world?

I think there is a slim chance they might show hints of next gen stuff, but it will be slick like Ubisoft's Watch Dogs and you aren't quite sure. It would be a good time to show a complete new IP.

Killer Instinct!!!!!

not so sure big ben.  Forza looks to become a COD, yearly release. remember turn10 released last yr. with another studio releasing it this yr.

i think Fable is dead to MS. 

the next GEARS after judgement will be next gen., and i think there's a chance we'll see it go multi-platform. i'll dream about it. whtever MS announces will likely be a new ip.

Maybe they will show. Next-generation gears and halo4 that would be cool

Gears 4 impossible.
Halo 5 impssible.
Forza 5 unlikely.

We do know we well get a new trailer of Gears of War Judgement and a trailer of Halo 4: Spartan Ops (most likely mid-season trailer. Since a Season 2 is unlikely to be announced when the first season only have 4 of 10 episodes released).

Pretty much:
Gears of War Judgement
Mid-Season Trailer for Spartan Ops(Halo 4)
Destiny(the new IP of Bungie)
A sneak view of the next box?
