Why? Has there been a shortage problem with Gamestop?

My little brother pre-ordered with Gamestop so he could get it at midnight, and there seemed to be more than enough copies for everyone when we went last night.

I actually pre-ordered my own copy from Amazon (Conveniently, it shipped from the Amazon warehouse in Nashua, NH to my house in Nashua, NH)

Sadly I pre-ordered this so long that it's being shipped to my old address. Not sure what to do about that...

I pre-ordered from Gamestop and picked up two copies pretty quickly after midnight.
