Its most likely way too early to see any real deals on it yet. I get it early every year (I cover the NHL), but I always buy a copy for my cousin for his birthday. Give it until about the week of the 20th and maybe someplace like Newegg or GoGamer will have a few bucks off of it. I wouldnt expect much more than that though.
Oddly enough, Amazon doesn't even have it available yet for pre-order on the 360, but they have it available for preorder on the PS3 (59.99).
Will be interesting to see if they keep Kane on the cover. It'd be easy to replace him as they could just use one of the European covers here.
