Pocketbook-Global have announced a new education platform for the Russian market. It's based in part on Pocketbook's 9.7" ereader, but it goes beyond just the hardware. P-E is intended to assist the entire educational process. It's not just for reading; you can do other activities including homework.
In terms of hardware, though, it sounds like this is a completely new device. It has Wifi, Bluetooth, and it obviously has a touch screen, but there's no mention of the 3G connection on the 903.
