I always wanted to get this game. Unfortunately between my PC/PS3 library, I just got too many damn shooters man :D
That and you just can't help but get worried about the life of a game intended to last long in a crowded genre.
Shipping and tax on this is killer. Only 7 day shipping is free other options will cost, tax is something monstrous, total came out to 295 in the end anyway. Shop around first.
I think it's just a temporary thing to get the most sales as possible while its hot. Amazon had $20 gift cards for this on preorder, I don't expect them to lower the price AND tack on credit for it already.
