It's made by the original Socom team....The Socom on ps3 now is done by a new developer - Zipper, the guys who are making this MAG game, were the original developers of all the other Socom games on the PS2.
Other than that, they say that these battles and skirmishes can last up to an hour or more - so it's not like you can hop on, join a team and be the first team to 20 kills and then the game is over..It's essentially trying to be as realistic as possible with intense and long battles and firefights...286 people online battles i believe? Thats f'ing insane. Multiple units and squads in each division....it will be sick.
My only complaint thus far is that, as of a few weeks ago, they decided to go with a 1st person view. It may be just me, but I was hoping for a really sweet 3rd person game ala' Socom that would take the shooter genre up just a notch...but, alas, they decided to go with 1st person...like..everything...else...ugh.
KZ2 is a good game though, in my opinion...Lots of complaints about the controls, but for me, I thought it was/is a damn good game..I need to get back on it, it's been awhile since I've played it.
