Today I walk into work and read our daily store informer. In it we got a message from corporate passed down from MS.
Due to massive demand and excessive sales the following are all sold out WORLDWIDE. We are not allowed to take anymore pre-orders.
Legendary Edition
Limited Edition
Halo Reach console bundle.
We still can take pre-orders on the standard but have been notified that maybe only for a week more. MS itself can't manufacture high enough volumes to meet demand.
Expect Massive software numbers and a pretty huge hardware boost come September 14th guys.
EDIT: I'm not saying that we WILL sell out of regular editions. I'm sure we will be able to meet demand, but for those posted above either find another retailer or your out of luck.
