I don't know if I've been completely asleep at the wheel here for the past four years, but on the off chance that I haven't, VGC still tracks numbers sold.
Whether MS shipped over 15m units in 2011 really has no bearing on the VGC numbers.
Don't know how long it will take for all corrections for 2011 to be settled, but it's probably still too early for any more smug posts.
