I recall they lost a bit on selling the consoles to the USAF that were used as computer cluster. (The consoles afaik sell/sold? at below cost and rely on games to make up the extra cash) So they lose money on consoles that aren't having games bought.
The consoles were reportedly selling at a profit (at least in the US) by 2009. Reports about the USAF condor cluster surfaced in 2010.
