Was thinking about the not so huge software sales increase for PS3. Could this be evidence to suggest that many of the new owners were not buying games with the system, which would in turn suggest that many of the sales would be from people buying a second PS3 or a replacement for thier current fat model?
Don't forget blu-ray, and also when you buy a new system with 3 years of presence… generally you found a lot of second-hand games so why buy full 70€ games when you can found these for 40€ or less in the same place?
