Guerrilla isn't one of those developers that takes a vacation the instant their game is out the door.
Changes and improvements will be coming "shortly after" the title releases on February 22, and they're all listed over at the game's official site .

Here's just a sampling of all the fixes that are headed our way:
That's just a taste; these guys clearly want to produce the single most stable and entertaining shooter experience possible. Don't forget that Guerrilla also clarified the Killzone 2 server issue; they won't be ditching those multiplayer servers just because the new title is here. In general, I don't think we can cast too many aspersions on the way this studio does business.
