Gamestop should be safe because they sell a very limited quantity to begin with. I'm pretty harsh on them but I think they're pretty well organized when it comes to these types of things. I assume they order a certain amount, and allot them accordingly to each store based on market reserving a large portion for online orders. If you don't claim a copy within the first few days, they run out. As I've said before I missed out on a few special editions waiting too long. I remember picking up the MGS4 limited edition a few years ago only because someone cancelled out on their preorder on launch day. Wal-Mart doesn't surprise me, but Best Buy does... that piss poor managment for a company that has been losing sales against Amazon.... whom I believe also stopped selling them within 24 hours. I believe Gamestop and Amazon are atop the priority chain, and if they start cancelling, I'd have to put the blame on Bungie for either production issues, or a miscalculation in what they promised to retailers. Wal-Mart is definitely at the bottom of that chain... never preorder from Wal-Mart... EVER.
