There's a small posibility that the game will be sold on Monday. Word out is that some retailers might get the game on Friday but start selling it on Monday-Tuesday morning.
Probably depends on the store, but all the EBs should have it Monday.
I was told that I could pick up the game on Monday after 7pm, and that they were only selling the game to pre-order customers. Tuesday anyone can purchase it.
My EB said Monday at around 7 as well, interestingly enough they are only getting a rather small allotment of copies(considering the scope of the game) in the initial shipment. With a bigger shipment arriving wednesday or thrusday.
