I was driving up from South Florida and decided to give tse a call. We couldn't get together, but we talked about a variety of stuff including their newest product. Scott said it is ok to talk about. Well, VDC now has a LED dlp.
http://www.vdcdisplaysystems.com/ssl6000.html
Hopefully, Scott will chime in with some info. He seemed pretty complimentary of the technology. A nice aspect is that the LEDs don't cost anymore than the lamps. Unfortunately, they don't have a lot of light, but they do last a long time with consistency.
Having seen these at Cedia, LEDs do look nice. I still think there is some work to be done in developing the technology. I can't wait to see what it is in store at Cedia next year. LG has a sub $1k SVGA LED pj. Maybe there will be an inexpensive 1080p LED pj next year.

Wow that certainly has long life for the light source. Any info on ANSI contrast and Lumens or did I miss that??

Oh, and no color wheel because there are 3 LED's RGB pulsed at high speed .

Keeping with the Marquee tradition....It certainly is stylish.

500 ansi lumens!!! I don't think you could have the room dark enough.

The LEDs themselves have 3k lumens. According to Scott, the optics brings that down to around 400. I will let Scott chime in on this, but he says you can go higher. Unfortunately, you can't get something for nothing. Another good thing is that they are consistent. With a regular bulb machine, the variation in light makes blending and stacking difficult. I would guess that if someone wanted to stack three of these you could have enough light output.

That's 500 **ANSI** lumens, not peak lumens. That's about double what most CRTs deliver. E.g. G70 throws 240 ANSI lumens, Marquee 8500 throws 225, etc. G90 is around 250-280 if I remember right. 500 ANSI lumens wouldn't blind you, but it'd be way bright in most of our HTs!

Actually if you go check out the Samsung HL61A750A1F RPTV in electronic stores is uses pretty much the same light engine with the same LED. Granted it will look better in terms of brightness but will give you a good idea of image reproduction.
Also the Samsung HL-T6187S and Samsung HL-T5089S

I thought I did in my first post. I think they look pretty good, but if you have a nice CRT set up then you won't be switching tomorrow. If you are in the market for a digital pj, then the LEDs are still to expensive at over $10k. If you wanted a digital in the short term, then I would say get one of the cheap LCDs or dlps.
Gary,
I think a better way to look at it is ft/lmbs. Most of the ones at Cedia were in the single digits and the screens weren't that big. What most of the manufacturers talked about is that they looked brighter than the lumens on the screen.
As for the look, I think they just wanted to get it into a box and get it ready to ship. Also it has to be built Ford tough for the military. Ok maybe something that is actually tough, how about Marine tough for Ron. 
Mac,
Yes it is to damn cold. I think it is really around 20F and that is to cold for me. I guess I am not Marine tough. The only beaches I wanted to storm wer in the Caribbean.

It's about time! I've been seeing LED lighting as the obvious future choice for projectors for years. They're only going to get better,
brighter, and more efficient as time goes on, too.
However, I tend to believe that the SSL6000 uses a different light path than your illustration. I think that it keeps the R, G, and B outputs
separate and directs them to their own DMDs directly, and the output is combined and sent to the lens. There is no reason whatsoever
to take the R, G, and B LED outputs, integrate them to white, and then re-split then back to separate R, G, and B signals.
A conventional 3 chip DLP unit uses dichroic filters in each DMD circuit. It's not necessary when you have three discrete color lamp
sources.
But it would also require a different physical configuration of the DLP engine if you used three separate lamp sources, one for each DMD.
I'm not sure how that works out in terms of differences in manufacturing cost.

This is not how the process works. It does not mix to white prior to DMD contact.
RPTV LED DLP has been available since 2006 so its not new technology. And I already have service data and repair info on these.
There are also other brand projectors coming available.
And although 3 chip is possible I haven't heard of any yet and the Marquee is not specifying that.
