I have a feeling that it'll be just as good as Battlefield Bad Company 2. I don't really think it'll be much better than Bad Company 2.
And personally, i played BF: Bad Company 2 for a month and then i never played it again. So if you liked Bad Company 2, you'll probably like this. And if you're tired of Call of Duty games, you'll probably like this too. I won't be buying it, but i'll rent it. Actually, GF already shipped it to me =P
