That might be their previous light engine. Colorlink, whose design I believe is shown in the video, now has a newer one on their website called the CQ3. They don't show the Quad anymore.
I don't know for sure that JVC actually used the Colorlink engine, but it is a pretty good guess. The CQ3 has fewer parts, which may help explain the significantly lower MSRP for the new sets.
Of course, I could be all wrong.
