I don't believe Gears 3 will be shown at E3. I believe that BIG Halo ODST will be done, including more video, with comments for people to try it out on the floor. There will be other news also, and the 5 minute surprise will be revealed. I expect more Live Arcade stuff will be mentioned, discussion of total content, and a bit of a blurb pushing both Live Community games, and people developing for them. You will get the Live Arcade/Community game montage.
Also, expect the unexpected.
