The Xbox 360 is doing well. 50% up on the Xbox 1 is no mean feat and all at a higher sale price to boot. I don't really question the idea that the Xbox 360 won't be up for the last time this year as they could either release Natal with the console and no price drop or cut the price of the console and sell Natal seperately it doesn't matter.
But I do believe it will be the last time, unless Natal is something special the console is teetering on the top of its lifecycle and its all downhill from here.
Tease.
