Just to expand on this point a little . . .
Each of the features in a product development project will likely be amortized by JVC (or any other company for that matter) over a period of some number of years - usually the period in which the product is projected to have a useful like.
So, if JVC expect that the RS_ light engine, for example, will have a life of, say 6 years, the development costs will be spread over that period (or perhaps some other period as required by accounting principles).
I am sure that JVC is in the "milking the RS_ line" for profit stage, so it is unlikley that we will soon see any breakthroughs, assuming further developments are being funded.
It is my belief that many DLP manufacturers have been in the "milking the product for profit" stage for many years now or have simply become repackagers of TI developed technology. When will we see a new, more flexible, lens from Marantz, for instance? That would probably take some development dollars that Marantz may not be willing to spend, or perhaps may be seen on some future product.
