according to official shipments, PS3 surpassed Xbox 360 back in December 2012. Factor in how padded the 360s numbers are due to multiple purchases via RROD, and the PS3 surpassed it way before that. Not "officially", because only shipments and sold-through numbers matter to investors, but unofficially in the sense that more people own PS3s worldwide than 360s

Rrod units can't count as sold. That is lying to the shareholders... Which you just can't do. 

If I buy an Xbox, that counts as a sale. If the Xbox breaks a year later and I go buy another one to replace it, that counts as another sale. It doesn't retroactively revoke the previous sales. 2 units that MS shipped out were bought. It doesn't matter to them if 2 people bought one a piece or 1 person bought 2. It's still 2 units sold.

well even if more 360 sold more units, due to rrod the install base of the ps3 is still larger.

article staes that 30% of the first waive were afected before the black slim. and then again afer the kicknect was released. im guessing at least 10-15mil should not be total install base.
