I guess I don't follow the reasoning behind Sanyo (or even Epson) for bringing out a brand new projector with D7 organic panels, despite it being lower cost. Last year the 1080p low cost leader- Mitsubishi HC4900, using D6 inorganic C2 fine panels, were selling for under $1,400. Those D6 panels are also used in the current Mits HC6000, a very good projector. If they wanted to save a few bucks I would think they would have chosen the D6 inorganic panel over the D7 organic panel, despite any contrast gain.
While it is true some people turn over projectors frequently and may sell their projector before the panels start to deteriorate, the big question is who is going to buy them used? I certainly would not buy a used projector with organic panels given that I could buy many more made with inorganic panels.
