After researching the newest battlefield installment here is what I have discovered:
1. PC release date: August 31, 2009 (already out on PS3 and XBOX)
2. Download only purchase costing $15
3. Consists of 3 maps (which all 3 were originally in 1942)
4. Uses the new Forstbite engine which allows for destructible environments
5. The game is defenitly focused on vechicles
6. Servers maxed out at 24 players, so limited to 12 vs 12 (hopefully they will expand for PC but doesn't seem likely)
7. 3 classes - Infantry, Scout and Sniper (note: no medic)
8. Game features an auto-heal. Same as we are familiar with in Call of Duty series.
9. Only one game mode: Conquest (I don't remember any other kind in the other Battlefields so not surprised)
10. Developers haven't rejected the possibility of addons later.
