I think the 360 version has AA but the ps3 version has some added shadow effects and a free DLC level. If you don't mind some jaggies get the ps3 version, otherwise get the 360.
The walmart in Watchung does have it however. (Or at least did around lunch time when my wife picked it up for me today). Where do you live btw? I'm in Piscataway.
