InFocus's high-res candidate, the Play Big IN76, comes out in February, and should list for about $3,000, a very competitive price for a 720p resolution HT projector. It is supposed to be available in February.

The IN76 uses Pixelworks’ DNX video-processing technology and the 720p DarkChip2 DLP from Texas Instruments, boasts 1000 lumens brightness and a 3000:1 contrast ratio. The new projector has a six-segment color wheel and has a DVI/HDMI connection along with all the usual other video inputs.
Optoma's answer is the HD72 home theater projector, which will also ship in February, but is expected to cost under $2000. It too features the Texas Instruments DarkChip2 chipset, has a 7-segment color wheel, and HDMI connectivity, along with the usual video inputs.
It will be interesting to see how these two products do against each other in the market, given the incredible successes of their entry level products over the last year, especially with the HT projector market expected to boom this year.
