First is an article show the greatest failures of e-Ink:

First off the top they list the Readius.
Then an article 'comparing' Kindle 2 with 'the rest' of the e-Ink market:

Seems to be a slanted article and misses a good share of the market. Their graph looks like it could have been cut from the wiki.
Next up is their wish list for a Kindle 3:

I'm actually surprised that color wasn't the FIRST thing on their list but it's in there.
And in case you missed it when it was posted here before, their article on the future of color e-Ink.

Again the comments on DVice often have more information on the articles, this time with the link to the youtube video we've probably all seen with the interview at e-Ink covering color displays.
Though the interview is over a year old and they were saying then 3-5 years, shouldn't they now be saying 2-4 years? I still see the comment in articles (like the kindle rollout) saying 3-5.
