I.don't know why but they stopped development on a single chip LCOS solution years ago. Ideally, if the chip is fast enough, It can do sequential color and be fine with motion. Maybe that was why they didn't have any real production units.
I don't think it's so easy to develop faster chips. To make them switch faster you would probably have to make them thinner (I read this somewhere but can't recall where), which in turn would make them less good at blocking light. i.e. they would take a hit in contrast. Sure, they could take Sonys route, but then probably have to start from scratch with a new chip and might not be able to get more contrast than Sony anyway?
Regarding single chip LCOS, the switching speed requirement is very high. Now they can't even switch fast enough to do 3D without ghosting at 120 hz. A DLP with a 5x color wheel is working at 3x (RGB) 5x (wheel speed) x 24 Hz = 360 Hz.
DLPs are inherently about a 1000 fold faster compared to LCOS, which also explains why they do not suffer from any ghosting.
If they could make a laser LCOS I would be very happy with that. If I understand it correctly the very low etendue of the laser would make it possible to close down the iris fully without light loss. 1000-1500 calibrated lumens that doesn't degrade over time coupled with 150K:1 native contrast seems like a very powerful combination to me. In addition low etendue makes it possible to use much simpler and cheaper optics without degrading image quality - i.e. much smaller lenses could be used without affecting sharpness.
I have an X35 at the moment and a 119'' high contrast high power screen. I wouldn't mind even higher contrast even though it's quite good already, and a bit more lumens in 3D would be nice (it's very nice and bright in the sweetspot and in high lamp, but that's noisy and with a new lamp and it's less good outside the sweet spot.). Otherwise I'm very happy with it. Sure, there are some ghosting in the most difficult scenes and it would be nice to get rid of that, but it's rarely visable and I love watching 3D on the machine. I have a Panasonic 55VT50 as well and the JVC kills it in 3D IMO. The image size is of course very important, but in addition to that, the panasonic has very poor black levels in 3D mode and more noticeble ghosting compared to the JVC. The high contrast of the JVC really kills the tv and makes the experience so much better.
