For MS to suggest their WW launch is "just as good" as Sony's NA launch is simply disingenuous of them (and not for the first time).
Sony sold every machine available in NA and has months of pent up demand, this will be followed by an equally large, if not larger, European launch. Once again, demand is so great every console is accounted for well into the new year.
MS went with a WW launch, some territories received little stock, and I know from my experience today, consoles are still available in stores local to me (UK). By all accounts, it's a similar situation in the US.
Of course, this will become quite clear in the coming weeks and months, but MS were always going to put out a PR, claiming some record or other.
Edit, of course, no ones even mentioned Japan and the Asian market..............
