I bought a 16GB from Newegg and had the same problem.
I called Newegg up a few days after it said delivered and still hadn't showed up. They put the request in to investigate, about 7-8 business days later, Newegg shipped a new one. I received that one.
No Best Buy store near me has these in...
I picked up the CE at lunch today and did not receive a the preorder code.
There was a dude there who had been waiting for over an hour while he was on the phone and an associate was on the phone.
They kept telling him they were emailing him a code right away, but he never got it. Eventually...
Looks like I'll be canceling GoW Ascension and Injustice preorders from Amazon and getting them from Best Buy. Especially since Amazon doesn't give the credits to people who buy the CE/LEs.
May also preorder Last of Us, Dead Island Riptide, and GTA V. Haven't fully decided on those yet.
