Yeah usually most places say "Your card won't be charged until your item ships". Of course they could just be placing a hold, and not charging it yet.
Yeah Wal-Mart has seriously jumbled the whole NCAA Football 11 release up. The paper says the 6th, the local ad on WalMart.com says July 13th, but when you roll over it it says July 11th. That's three different dates they are throwing out. I'm also not sure why Gamestop says "The release date and price have not been confirmed by the publisher and is subject to change" even when it says July 13th.
Anyway, all of that said the
NCAA Football 11 Twitter states: "The release date is still July 13th."
