I called Apple today about this because mine is in the same position. The Apple rep called Fed EX and here is what he told me:
"Sir, you're not gonna be happy with what I'm about to tell you. Apparently, China is celebrating the Chinese New Year, and everybody is off of work for about a week. It won't ship till later or next week and there is nothing we can do about it...we're sorry...etc..."
I called because the estimated delivery date was for the 11th which got me upset since that was a week away. This is why, everyone is in the same boat now. It sucks, but there is nothing we can do.
