Well, it is possible that a lot of Gamestop's don't know that they have them. We have a store here in Mpls that gave out a couple of figures with pre-orders earlier in the week. I went to get mine yesterday and they told me they didn't have them, but would give them out when people came in to get their games. i called back today to discuss the situation and the same person who told me they had none confessed that they do have them in stock, but that her employees mistakenly gave them out ahead of time and wouldn't be giving anymore out until people came to get their games.
Just some food for thought on why your local gamestop might not say they have these:
A.) They really don't have them
B.) They have them and don't know it ('cause they aren't supposed to give them out yet)
C.) They're just giving you a line to avoid complaints and plan to give them out with the games
And of course, I sometimes assume the worst in people, but what would stop a Gamestop Manager from just keeping the case(s) for themselves and selling them online? There doesn't seem to be any tracking of what has been handed out so far and most of the GS's I spoke with didn't know what the hell I was even talking about.
