GoW:A will drop to $10-20 within a year. No point in gambling with BBY to hope to get to that price, especially with the stricter policy. Not a knock of the quality of the game...it happens to all GoW titles and the multiplayer aspect of this one doesn't seem compelling enough to keep it from plummeting in value, much like Kratos keeps plummeting down to hell ;p
I don't really see how that is relevant for people thinking about pre-ordering a game. Nearly every game will be $10-20 in a year. Someone contemplating pre-ordering a game is obviously not wanting to wait that long to get it.
