That's the theory but there seems like an obvious problem with it: The x64 desktop and server CPUs are basically the same designs as each other and they're selling plenty of servers, so they're going to keep designing new ones.

Meanwhile people who can't afford new systems because of high prices don't buy them, but that only creates pent up demand while people continue to use their existing systems. Then as soon as RAM prices get back to what they used to be, all the people who have been wanting a new PC can suddenly afford one again and instead of having below average sales they get catch-up demand.
