Actually Sony might be able to deal with a 100$ price cut at this point fine as the amount of games available is much bigger now and thus the amount of money they recoup from game sales should be quite a lot bigger than what they had just one year ago. And with the wider selection the chance that someone buying a new PS3 also picks up 3-4 games is bigger, which should help balance out the loss.
That said I agree that the current price is not bad, you are getting a lot more than with the competing systems. The problem Sony have though is that they have struggled to educate the market on these advantages (Blu-Ray, standard replaceable HD, built-in web browser, printing support, mouse+keyboard support, built-in wireless etc.)
