I think the event will have a few game announcements, but I think they will talk about other stuff more, software, features, technology. But whatever ill throw in my wild speculation.
Well it won't be called Xbox 720.
Ghosts is cross gen, but with a new engine will look much better than any COD on PC before but still won't looks as good as Battlefield 4.
I think bungie will be at Microsofts E3 event, not this one.

I'm really excited for Alan Wake. Hopefully it wont be a disappointing sequel

Dont forget a "2nd" Gears Trilogy.

We won't see another Gears game right away. Epic proper is doing other things right now. But yes seeing what they are up to is deffinetly possible.
