The fact that it will be about a year till those countries get it officially that alone makes using. 360 numbers faulty unless you are trying to relay what the sales COULD have looked like and not what they WILL look like. Every week the XB1 sells out of those countries means that when it officially releases the XB1 needs to sell more than the same % as the 360 to have the same % in the end....
Basically... those countries it hasnt launched in yet will make up less % than the 360 did by default. It gets worse when the XB1 doesnt have a head start or price advantage which will hurt its sales.
