Dust 514 will have an option for keyboard and mouse control on the PlayStation 3, making it one of the few games to take advantage of that option on PS3. (Unreal Tournament 3 allows for KB&M play.) Given the game takes place in the same persistent world as EVE Online, the control option should come as a nice concession for those crossing over from the PC.
Dust 514 Base (via Joystiq) confirmed the support, and it was later reconfirmed with a tweet from CCP. The KB/M support does raise some question of how players using a controller will match up, since the control methods usually lead to a pretty steep skill disparity.
Dust 514 started accepting closed beta sign-ups last year. A release date for the title is still unknown.
