Atlus sent out an e-mail today saying that Dragon's Crown was pushed back to 2013. It's listed again on Amazon for $50 on PS3 and $40 on Vita.
If any of you contact Amazon regarding your previous preorder, please post back here with your experiences.
Eventually got a $20 credit. I think what did it was pointing out that someone else in the same situation had gotten the game for $30 after complaining. In case anyone is wondering, I actually did use the credit to pre-order Dragon's Crown again.
