The IDG News Service sent someone to the World Ebook Fair in Shenzhen (it's being held right now), and they spent a few minutes at the PVI booth.
PVI had 6" and 9.7" color E-ink screens on display. Unfortunately, the screen isn't nearly fast enough to be able to play movies at 30fps. PVI also had 3 different touchscreens on display, as well as 2 flexible screens. All of the screens have been demoed for Amazon and PVI's other partners.
This is going to be an interesting year. Liquavista and Qualcomm are each going to have an ereader with a color screen out by the end of the year. PixelQi has been hinting that they would release an aftermarket kit (no talk of an ereader, sadly). Now it looks like PVI's new screen tech might be on a device as well.
My money's on Liquavista. Their new screen is supposed to be nearly as cheap to produce as LCD, is close enough in tech that existing production lines can be changed over. Also, they're working with Texas Instrument's next gen CPUs (the ones with faster screen refresh rates).
