Ok, I emailed Amazon.

Good news, they adjusted my price to the new $529.99

Bad news:
"Regarding the rebate, your order will not be qualified for the rebate, your order must be placed in between November 16, 2009 - December 31, 2009 to eligible for rebate. If you want to take the advantage of the rebate, you may cancel this order and place an new order."

Is it worth $50 for me to get out and back in line? Hmmmm....
