I just wanted to post a few links to videos of the A6 & A9 (apparently taken at CES 2010). Quite a few reputable sites reported that new Jinke readers were renders only, and did not actually exist. A few people suggested that they would never appear. These videos obviously contradict those viewpoints.

The general consensus that the Sipix screen (versus Visplex E-ink) looks a bit darker, and the blacks a bit blacker seems to be the case.
