Check out the newest, and final trailer. Also probably my favourite. Let me know if you see it on television (or any SOCOM commercial) as I'm hoping they run it. SOCOM is one of those games that appeals to people who only buy 1 to 2 games a year, and you really nail that market if you get a tv presence.
Also, the game is out today! Some people already have it. I'm not one of those people. But in the mean time if you do have it, let me know what you think so far. My biggest question mark right now is match-making/party system since it wasn't in the beta. Is it in the final game? How is it working? Let me know.
