how many countries was the PS2 released into durring it's life cycle?
the fact that the PS3 and the PSP and the PS2 have been released into more countries world wide today than they were previous tell's you that there is more growth there.
28 countries world wide, now its 36 countries world wide that sony is releasing the playstation brand into
Have you taken into account Sony's competitors (especially the Wii) which are taking a bigger slice out of the markets the PS2 was released in? Also many of the newer markets are either second and third world ones, or because of neglect have a tradition of piracy, so Sony's competitors have the advantage of being lower priced and piracy on their side.
I really don't see how these new countries will compensate for the amount of marketshare that Sony has lost in the much larger and more mature existing ones.
