Personally, I could see this as being true even though it is a remarkably bad idea ...
Multiple SKUs are not typically a good idea because people generally become confused as to what the difference between the models 'really' is and simply gravitate towards the more expensive model; the exception to this would be that back in the day many consoles (SNES) were sold in 2 SKUs, one with just the system and another with the system, an additional controller and a game.
Beyond the confusion it adds I think the benefit the lower price would produce is minimal ... I think you can break the market into two unequal markets (1/4 and 3/4) where the smaller market is willing to spend more than $300 on a console while the larger market is not willing to spend that much money; the people who are willing to spend more than $300 can (potentially) be convinced to pay any 'realistic' price for a system given proper motivation. In order for the PS3 to really break into a new market and start selling better the Price has to be below $300 which won't happen any time soon.
