Most larger manufacturing companies move at a glacier pace. I could see Apple making a quick decision to use these and then having them in models within a year, but few other manufacturing companies are willing to move like that.
My impression was that Apple intentionally lagged the cutting edge curve to error on stability and sound user experience. I would be very surprised to see them go in the direction of moving parts - instead I would expect them to continue in the direction of all solid state (no moving parts) as much as possible.
