FYI: Optoma is also discontinuing ALL 480p projectors except the MovieTime DV10 projector. So, their very popular H31 and H27 models will no longer be around in favor of the new 720p models.
At CEDIA, the Optoma HD81 was one of the best valued 1080p projectors at the show and produced a phenomenal image on a 170" diagonal 2.35:1 screen. It was awesome to see an image so bright from a $7K projector on a screen that large. The Sony Pearl, which is a great value at $5K simply didn't seem nearly as bright as the Optoma, but would be perfect on a 100" or so sized screen.
InFocus basically showed nothing worth mentioning.
