The reason Sony keeps making the hard drive size of the PS3 larger isn't necessarily to justify keeping the price where it's at. Hard drives have a price floor, regardless of their size. If Sony wanted to sell the 40gb again for some reason, they'd still be buying 80gb drives and they'd be cutting them down to 40gb with the firmware.
That's what happened with the original Xbox, actually. The hard drives were not the same size when the system hit EOL but Microsoft artificially limited their size to make them match up with previous models.
This is just another way of saying that people need to stop bringing up the idea of cutting the hard drive size to save money. It doesn't work.
