Despite the fact that it is basically gonna be a demo, DICE still get lots of info from the "Beta", mainly to do with server loads, gameplay with full teams, plus the fact that it is the first mass console outing for the game. Also, it's easier to find bugs with lots of players playing at the same time, as well as the fact that, with so may different play styles, DICE get a lot of balancing information as well.
