Analyst predicts price cut for the PS3 this summer
"It is possible that Sony's cost of production for the PS3 has declined to the point that the company may consider a hardware price cut some time this summer, and we may see a price cut for the PS2 before the holidays."
As long as Sony's manufacturing costs have dropped to a reasonable rate, I'd heartily encourage Sony to drop the price of the PS3 as soon as possible. It's very clear that people desperately WANT a PS3, but just can't afford it. Dropping it to $500US and then marketing the hell out of the price drop would do wonders for their sales. Just look at what a 30 dollar price drop did for the PSP.
