Those are the Reflective LCD, aka R-LCD, models that Epson planned to get to market last year but failed to deliver. They are still in the product plan, but this year its about competing in the 3D arena and that means getting cost effective traditional LCD models to the market.
R-LCD is basically Epson's answer to LCOS, BUT even though they plan to get them to market there is NO plan to have a 3D R-LCD model.
The R-LCD models I think were designed to compete with JVC DiLA and the higher end Sony SXRD models and those competitors are already offering 3D. So personally I think the R-LCD will quietly miss this year again. Epson is introducing a new traditional LCD panel, the D9, which is the basis for all its new 3D LCD projectors and their main competitor the Panny PT-AE7000. The new D9 panel offers a faster refresh rate, 480Hz, and better native contrast than the previous widely available D7 panel.
The new 3D models are the 3010 (replaces the 8350UB), 5010(8700UB), 6010(9700UB) in the US market. The 5010/6010 are essentially the same model and will go by TW9000 in the European market.
