Global Battlefield Community Manager at DICE Daniel Matros states "A lot of what you are seeing in the BETA doesn't exist in the main game already. 1st Party submissions mean we couldn't give a version of the latest code in the BETA but the retail game is well ahead of what you are seeing now with a lot more bug fixes already in place."
YAY. I've played about 4 hours of the beta on PS3 and other than the bugs it's amazing :D
