Most of the large screen devices we are sure about are in the
E-book Reader Matrix: Larger Devices. I took out the Hanlin V9 recently, because the specs were so clearly out of date. There is little doubt that Jinke and Netronix will be releasing devices with 9.7" screens as soon as the "FlexiScreen" is available from PVI.
Pocketbook showed an 8" prototype recently, see
Video from IFA 2009: PocketBook 360 and 302 (touchscreen, WiFi, Bluetooth, GPRS...). Most of their hardware is from Netronix.
The PocketBook 302 (6" E-book Reader Matrix) is a good indicator of where high-end devices are likely headed, and most 8" and 9.7" devices will be high end because of their screen cost. It will have a touch screen, MicroSD/SDHC, USB host (memory stick or keyboard), USB 2.0 (charging), 3.5mm stereo, Bluetooth, WiFi, 3G/GPRS. Essentially every hardware bell and whistle you can think of.
