Kindle’s will (kind of) support ePub
Andrew Cunningham on arstechnica.com:
Amazon’s Kindle Personal Documents Service will now accept ePub files sent to your device’s Send to Kindle email address, the same way it currently handles PDF files, Word documents, and other image and text files.
I use the Send EPUB to Kindle service. While this news is not as great as native ePub support, it’s something.
