Will future Kindles use Mirasol displays?

Update: there's some new info on the Mirasol display. Qualcomm claims 6X power advantage over E Ink (even with color and video), they have a way to light the display, and it can be paired with a touchscreen.

Currently, all Kindle devices use E Ink displays. But now Qualcomm are readying their own efficient, fast, colorful, and cheap displays called Mirasol, and there are rumors that future Kindles might use this new kind of display. The current prototypes are 5.7" large, and should be ready by autumn.
