Everyone keeps goin about a BF3. I personally don't think it will happen any time soon.
Yes the people at EA/DICE did say they weren't forgetting us PC user's but they never did confirm or acknowledge the existence of a third game. TBH i don't even know where/when they would set a third game.
They've done WW2, They've done modern combat (BF2), They did the future and that turned out to be a flop....
The only thing we BF players have to look forward to atm is this patch, hopefully it will revitalize BF2 gaming a bit.
