Playstation domination shouldn't be such a surprise really, at least not at this price point. It's the 360 domination the should come as a surprise.
Remove the weekly sales of Japan for the 360 and the numbers won't change that much the same can't be said for the PS3 so Japan alone makes a big difference. PS3 wins hands down Japan.
Now for EMEAA, PS3 is supposed to be available in more countries than 360 so of course those country have no choice. PS3 wins in other countries.
Once those are cleared out, PS3 domination isn't that true anymore. The countries where both 360 and PS3 are available is either a "estastical tie" or mostly dominated by the 360 and the PS3 taking the lead in smaller markets.
Every weeks, the PS3 sells an average of 20-30k more than 360 to countries where it's not available and to Japan where 360 has no impact at all.
As for the Wii, now that it faces competition from Kinect and the Move, that it lacks new games and with the confirmation of a new console on the horizon, it's just normal that the sales slows down a lot.
That's not domination in my book. It's on par!
