Maybe, but with a 50% reduction in MSRP (and thus probably a reduction in street/overall cost), and given half the MSRP of the Optoma HD8200 (which is 0.65" DC3) I highly
doubt the W6000 is a DC3 machine.
The smaller (and higher CR as compared to the DC2+) 0.65" DC3 chip in concert with the significantly brighter bulb should allow them to tweak the optical pathway to achieve a significantly higher CR on the W6000 than on the W5000. Obviously 50,000:1 is a marketing number, but to say that the 6000 won't significantly outperform the 5000 is jumping the gun.
This just seems like an absolutely classic case of "to good to be true", 2x brighter, 5x better CR, and all for half the price. The math just doesn't add up. I just don't know how you can combine 2500 lumens and
anything close to 50,000:1 On/Off.
If I were to guess, I'd say the W6000 would be more like an Optoma HD808, which is spec'd at 15,000:1 On/Off and 1300 Lumens, and uses an (I think) 0.65" DC2 DMD.
The 8200 hits about 6500-7000:1 On/Off with DB, which would probably put the 808 around 5000-6000:1 (about 30% less due to the DMD), which is right in line with the W5000.
Additionally, most companies quote max lumens and max CR. It goes without saying that this PJ - just as every other commercial PJ out there - won't simultaneously achieve max light output and max CR, but the ability to trade high light output for high contrast (or have a nice middle ground) is very likely and not uncommon in PJs with manual irises (assuming they kept that feature).
No doubt, but just go do some research on machines that can do 2500 Lumens, you'll find pretty universally that they've got comparatively poor CR to those with lower specs. Reason being to get that much light you have to do things that sacrifice black level. And then there's the issue that these "cheaper" Dynamic Black machines seem to sacrifice Native CR in their implementation.
Also, for some perspective, this thing has a 280W lamp, the Infocus IN83 has a 300W lamp (different one granted) and can "only" do 1600 Lumens. So how does BenQ achieve 40% more? White segments? Or did they go with the RGBCMY BrilliantColor colorwheel? Either one will hurt black level.
Maybe we should wait to see some more numbers and some reviews before we dismiss the W6000.
I'm happy to wait, but I just can't get excited by something that seems so clearly designed by marketing and so blatantly obviously unlikely to come anywhere near it's specs.
Throw out the lamp, the high CR, or the low price from the stated W6000 package and I'd find it plausible and potentially interesting.
