They have released like five or six patches now in the span of a year (which is a whole hell of a lot better than Zipper ever did) and S6 has done a decent job of keeping the community informed, but for over six or seven months, features touted in the game's own instruction manual weren't even in the game. They finally just added clan tournaments and shit like that.
I really don't think there's going to be another SOCOM anytime soon. The game as it stands is pretty damn good now, and most of the bugs and glitches are gone (at least from what I have read).
S6 has been slow about getting some of the promised features out onto the game, but now that the game is fixed, they should be able to switch most of their resources over to content creation. I definitely don't think S6 has done as bad a job as many people think.
