The Mitsubishi HC6800 is sharp. I believe the HC6800 appears sharper than any of the other LCD projectors out there, but for their own HC7000. It appears sharper, than the LCoS projectors as well. I don't believe it's quite as sharp as the better DLP projectors like the competing W6000, but I'd place it closer to the W6000 overall, than to many other non-DLP projectors. I give credit, primarily to the optics. I say this because I'm guessing that by going with only a 1.6:1 zoom, instead of the 2:1 zooms found on most LCD home theater projectors, makes a difference.
It's not huge, but the HC6800 without doubt has a slightly crisper image than even my JVC can produce. Sure, we're splitting hairs, but, I'd say the Mitsubishi stands out over a lot of projectors in its price range, in this one area which is very important to a significant number of folk.

Please note, we are slowly switching to using the Playstation video logo as our sharpness example, instead of the old dts-hd logo. The original sample test disc from dts died, and they can't find me another.
