We've compiled an overview of forthcoming 2nd-gen e-book reader devices that are all based on E Ink technology. They include two readers from Chinese Jinke (HanLin V2 and V8), one from Sony (Sony Portable Reader), and one from Dutch-based iRex (iLiad).

For corrections or add-ons, feel free to post anything that comes to your mind in this thread.
Also my thanks to May from Jinke for sending me his version of the device matrix. If I had to pick one of the devices based on quality of customer service, it'd certainly be a Jinke HanLin reader.
