Gamestop does their Midnight Release thing by how many preorders that the one particular store gets in. It has nothing to do with a corporate policy. Case in point, the Gamestop on base here did not have a midnight release for Rock Band 3, Halo Reach or Red Dead Redemption due to the small number of preorders recieved at that one particular store, but the Gamestop at the mall just 3 miles away did.
