To be fair, you have to look at certain examples, one of which would be my parents, they don't play games but are huge video junkies. They firmly believe (and i won't disagree with them) that blu-ray will be the next big format, so they wanted a blu-ray player to go with their tasty HDTV. Being the intelligent consumers that they are, they did a fair bit of research, their conclusion was that the cheapest and best performing blu-ray player on the market was in fact the PS3, so they went and got one. The result of this is a hardware sale that will never have any software sales tied to it. If any game deserved to be the first 'best selling' PS3 game then drakes is definitely it.
Shame the buggers won't let me buy any games to play on it D:
