Again, never. Technically they may be able to do it, but there is probably no market for it - except you of course. The huge (expensive!) processor that's needed plus the constant screen refreshing would reduce battery life to hours rather than days or weeks.

A rough estimate:
The video you linked to shows what they call 'full-motion video' on only a quarter of a 6" E Ink display. I estimate they use some 5 square inches. That allegedly gives a battery life that is similar to non backlit LCD, which I think is 10-20 hours. If you want to have full-motion video on all of a 10" display, the area that needs to be refreshed constantly is almost 10x as large. So battery life would be reduced to 1-2 hours.
