Hold on, I just read through the last page, people need to cool it with the insane MS/EA partnership talk. Yes EA came out on stage at MS and not Sony's press conference, but that was to talk about sports, not Battlefield or anything else.
While there are rumors that this partnership involves more than just sports, it doesn't mean much for Battlefield. The people saying things like the XO version will have more players or will be vastly superior or things of that nature, no, absolutely not. Maybe it will have exclusive camos or early DLC, but there is no way the versions will differ in player count, FPS, anything like that.
My predicitions for BF4 at E3:
-Amazingly edited MP trailer AND a live stage demo at the EA press conference, similar to the MoH 2010 E3 presentation. (this was previously confirmed)
-64 players absolutely confirmed for next gen
-If they talk specs, it will be 1080p/30fps, 60 would he a nice surprise
-Map on the floor will probably be mostly infantry/urban focused so it is easily accessible for show goers.
-Behind closed doors presentation for the press will show off a different map. Large, lots of vehicle combat, and a perfect place to show off the new, improved, and streamlined Commander mode.
-Beta in September, like that poster suggested
-BF4 will be there day 1 on both next gen systems
I know most of these are gimmies, but I'm very interested to see what it is that they've chosen to show behind closed doors.
