Some of the developers involved with Battlefield 3 have been very active on twitter answer questions about the game. There is a lot they won't talk about or comment on since we are only in the very beginning of the game's reveal. I've gone through a couple of the twitter accounts and picked out some of the more interesting and commonly asked questions. Make sure you check out the full article.

What are the waring factions in the game? or is that still under NDA?

I'm determined to get an answer other than 'no comment'. Will there be sand in Battlefield 3?

One of the cities is Tehran... Yes, yes there will be sand.

64 is fine. Loved it in BF2. Why only 24 on the PS3 and Xbox 360 though? Hardware limitations? No dedicated servers?

we'll support as many as we can +maybe extra provided it maintains the integrity of the play experience
