The HC9000D is well loaded with features. All lens functions are motorized, there's support for an anamorphic lens. There's a full CMS (color management system) for calibrating the projector, and of course, support for 3D.
Speaking of 3D, I have yet to see/review any 1080p home theater projector that really has enough brightness to not be somewhat dim with 3D content, on a typical 100" diagonal 16:9 screen. We were unhappy with the JVC RS60, and also the brighter Sony VPL-VW90ES (about 30% brighter in 3D than the JVC). That's despite the Sony having over 200 hours on the lamp when we measured, which could mean an extra 10% more brightness with a new lamp. We still found the Sony could use a good deal more. Personally, I found that I could consistently watch content at the Sony's levels, but truly yearned for more brightness.
This Mitsubishi HC9000D projector is brighter than the Sony, but not dramatically so. After factoring in the extra couple hundred hours on the Sony's lamp, when measured, the HC9000D likely still has a 10-20% brightness advantage compared to the Sony. The HC9000D, so far, is the brightest, serious, 3D capable 1080p projector that I've seen.
