That was as of April. Reports now put Ps3 at over a million out in front of 360 worldwide.

So much for them maintaining that lead for the rest of the generation.
Gran Turismo 5 is the best selling game on Ps3 to date too with over 6 million sold (And since Ps3 hasn't hit 60 million yet, the attach rate is even better then the GT games were for Ps2.. for now).
Kinect is obviously killing off move due to it being a package deal with the 360, but it hasn't been enough to give 360 that boost to keep it's lead over Ps3.
