Wow, thanks, everybody. Wasn't expecting such feedback.

Sorry, I can't let that pass. Why does people believe in bad things so easily?
If you will read further Tom will explain that his first measurement was compromised by the LEDs which were illuminating his screen http://www.avsforum.com/t/1254103/new-mitsubishi-hc-9000-full-hd-3d-and-lcos-panels/270#post_20391135
20000:1 is a number confirmed by many trustworthy reviewers:
measured 19000:1 - 24000:1 based on setup
measured 19000:1 - 33000:1 based on setup (last value is with iris half closed at -9, maximum throw distance)
kraine measured 19333:1
and so on.
Contrast is one big plus which puts this projector above Sony HW50 for me.
measured 4000:1-6900:1 based on setup
measured 5600:1 - 12700:1 based on setup (last value is with iris fully closed, maximum throw distance)
measured around 4600:1
These are measurement taken by the same people in the same setups so I think it's trustworthy.
JVC has even more contrast (30000:1 - 40000:1 for X30) but is has a lot of negatives which pull me out of choosing it: big input lag (80+ ms), worse motion resolution, even worse 3D, color problems, lamp brightness problems, yellow/magenta banding, spots etc. Of course I could assume there are units without such problems. But at that price point I wouldn't gamble it.
In all fairness, Sony HW50 has 30 ms input lag (the best among LCoS projectors), but HC5 is fairly close at 40 ms. 10 ms is not worth the trade for 20000:1 vs. 5000:1 contrast. While 40 ms is a good trade for 40000:1 vs. 20000:1 contrast when we compare it to JVC. I wouldn't be able to play on JVCs at all.
Re. the Optoma HD8300. It has an upward throw and less placement flexibility. Also where did you see such contrast ratios? I saw around 1500:1 somewhere. And the DI is reported to be quite useless.
Things weren’t as great when it came to contrast ratio. Without any electronic aids, the projector’s maximum light output was a rather paltry (by today’s standards) 12.9 ftL, and its black level was a fairly mediocre 0.0088 ftL. That adds up to a contrast ratio of 1,466:1. Enabling both the Image AI lamp mode and Cinema 2 iris mode increased this to 10,825:1, but as with all such enhancements, there were visible pulsing artifacts as it tracked the video.
All in all, I'm leaning towards HC5 more. I can see new HDMI 1.5 on the horizon and with it a 1080p60 3D projectors. Then I would probably buy a DLP and reap all other fruits such as 144 Hz 3D for 24 Hz content, better contrast ratios, better FI.
