It should also be noted that the prices on things like controllers, casing, packaging, shipping, etc. will never drop much in price and in some cases, will actually raise in time (anyone who has dealt with raw materials knows the crazy price fluctuations in steel and plastic over the past few years, thanks China). The initial cost is the real setback in situations like those (molding, tooling, etc.). While those things might not seem like they cost much, they definitely add up when you factor all of it together.
Moore's Law is not applicable when you're talking about an entire electronic device. They don't halve every 24 months.
The one exception here is probably Blu-Ray. Since it is such bleeding edge tech, the manufacturing cost will drop like a rock until it hits a saturation point.
