Both the PS3 and Wii went became available for pre-order this week at GameStop and EB Games stores. But will this guarantee you a system on launch day? That all depends on the store actually.
My local EB Games store is guilty of taking more pre-orders than they can handle. What that means is even though you pre-ordered a console, showed up on launch day early in the morning, and generally went out of your way to make sure you get a system, you can’t. Now, again this depends on how the store handles the pre-order list. My local EB store does it by list order, not who shows up first.

I have nothing but love for the local GameCrazy. GameCrazy is not taking pre-orders as of yet, but there’s a reason. They’re waiting until they know how many consoles they’re going to get. Once they know, pre-orders open up. No stupid horror stories. They even have a pre-pre-order list, meaning they’ll call you once pre-orders are open.
What is the pre-order policy for whatever game store that you frequent? Does you local EB Games store smell like weed and have terrible service like mine?
