Seems like ePUB is getting more and more hardware support. Our own company, Kolporter, is going to release eClicto reader with ePUB support.
eClicto size: 118 x 188 x 8,5 mm, weight: 174 g. SD support up to 4 GB. ePUB with DRM will be supported and non-DRMed PDF, TXT, HTML. mp3s/audiobooks, picture viewer (black and white, because it's said to be e-Ink). The price is expected to be under 300$ and the device is said to hit the market in September. They are planning to release platform with DRMed ePUB books to buy (although one can expect them to be mostly in Polish).
There are also rumors about bigger version: 10'' touch screen + WiFi and GSM module.
