No clue on why. Maybe they are just not a big market for PS2s (if they do effect the numbers, they might add another half a million, instead of a million).
But, I seriously don\'t know.
Anyways, shipped or sold, these are still good numbers. Now, if they are shipped. not a s good as sold, but even then, I\'m expecting, 15 or so million sold through since I doubt there are 3 million-7 million sitting in store selves and warehouses (though, they probably are stacking up for the holidays though [which, unless things improve, its not going to be a very happy one for any company]).
