Yeah it might be a good year for ebook readers in general...the most likely advantage being lower costs for same-old e-ink devices.
2009 was year of the clones...I hope 2010 moves forward a bit. Too bad Mirasol isn't slated for release in devices in the first half of 2010
Don't know at all about Liquavista though.... Don't really care about EPD until it is faster and more readable.
