Just saw this over on Gizmodo:
Fujitsu ereader with color
The article didn't say whether it was e-ink or not, but I'm guessing it is because of the refresh time. At this point, that's just a guess, though.
The link to gizmag calls it e-paper. (Ah, missed it the first read-through, but the article refers to liquid crystal display...)
Edited to correct the gadget blog I actually read this on. Sigh.
