I forgot Namco Bandai! Thanks, Axumblade.
Namco Bandai - 33.12 million.
It has been added to the list.
Edit:
And technically, Serious Frustrating, Microsoft is more impressive in that manner
Sony has both Ps3 and PsP to work with, which is a total of 76 million hardware units, whereas Microsoft only has the 32 million X360s.
(Although I wouldn't put too much into this way of thinking, I felt like pointing that out).
