OK, What is the Deal?

Why is it that the official Rush store and bestbuy.com have the Blu-Ray of Rush's Time Machine 2011: Live in Cleveland on sale on November 8th, and Amazon shows it not shipping until December 20th?

If it's an exclusive, that makes sense, but nobody's announced that there is an exclusive. Amazon has the DVD and CD versions out on the 8th.

God knows, I MUST have this the day it comes out!!!
