Update: Sony has replied to our request for confirmation of the May 2011 date for Killzone 3 with "no comment".
Original: CVG's reporting that Sony's already pinned down an internal release date of May 2011 for Killzone 3.
The only date officially given so far by SCEE is just 2011.
The site's also reported that it will support PlayStation Move - something Guerilla boss Herman Hulst avoided answering to VG247 during a recent interview at the game's formal reveal when asked if the motion device would support the shooter - as well as two separate co-op modes for two and four players, with the four-player co-op mode "objective based".
CVG's source also claims that the game's multiplayer will feature vehicles in it, although hasn't actually seen them in action.
Guerilla wouldn't budge when it came to multiplayer at the reveal, but Hulst told us it would be discussed ""later this year".
We've asked SCEE for comment.
