Maybe, but the PSN download for the beta was 2 gigs.....
I think it needs a cheaper price. It's a fun game and all, but I don't think it's worth the full $60 price tag. Heck, at least with Warhawk $20 of my purchase went into that bluetooth headset that came with it and I used it till the day the ear clip broke (or there was also the cheaper version sans the headset). Heck, with Socom you could say that the game itself only costs $10 of the new price if you get the headset bundle since the official PS3 headset costs $50 on it's own.
MAG doesn't have something like that and it's already a hit or miss game with people as well as a game that would benefit from people using mics (but a mute button is needed.... I don't like the current method of putting people on your block list).
