Amazon's got the pre-order up already, but the online download version is handled exclusively through Origin. (EA's version of Steam) I doubt you'll get a discount for this game, though. Supposedly the digital deluxe and collector's editions are limited in number though, so if you want either of those, I'd order them now.
Rams bet status: honored. Bradford still sucks.
RedAlice is right.
