May be a while before they announce a BF3, they just recently announced another game called Mirror's Edge, which looks pretty cool.

Not much info has been released about it yet, except that it's heavily influenced by Parkour ("free running"). Probably cashing in on the Assassin's Creed craze, but I expect DICE to make a decent game. Let's just hope it has native widescreen support (unlike BF2/2142)
