I think people will buy the PS3, don't get me wrong...but they have alienated a huge amount of their fanbase (teenagers), most of whom don't have the kind of job (if any) that would really allow you to make that sort of scratch to blow on games and a system, especially if the games do indeed cost $80 USD as projected.
With the X-Box 360 able to play most of the typical sports titles (Madden) and other general ones (GTA), I think Sony is in for a real shock when they realize people can buy the 360 for more than $100 less and get pretty much the same thing.
