Amazon has Xbox One pegged for the 27th November

Amazon.fr has it down for the 30th, so I reckon we are looking at the following
13th November: PS4 - US and Europe
27th November: XB1 - US
30th November XB1 - EU
Advantage Sony if this is right. You would assume these are going to be supply constrained, hopefully Sony can get a second shipment in by the XB1 launches and the weekend of Thanksgiving and Black Friday
