Nintendo has sold over eight million Wiis in the seven months since the games console's worldwide launch.

That astonishing figure places it within touching distance of the Microsoft Xbox 360 , which has only chalked up 11 million sales despite launching a whole year earlier. But both Nintendo and Microsoft are way ahead of Sony, which has only sold four million of its PlayStation 3 consoles so far.

With the Wii outselling the Xbox 360 two-to-one and the PS3 four-to-one, it's only a matter of time before Nintendo finds itself in pole position once again. It already has the lead in handheld sales with the Nintendo DS shifting 45 million units worldwide - more than double that of the Sony PSP .
