After hearing nary a peep from the Art Lebedev guys about their Optimus Popularis keyboard from years back, they've taken to their LiveJournal (LiveJournal!!!) blog to say production will begin "later this year", with "the release likely in 2011".
That'll give the Popularis a three-year gestation period, so we're expecting a lot from this non-OLED keyboard. More details have been promised for June, including some new mock-ups. [Art Lebedev via Slashgear]
