Tom Stites (JVC guy) told me 2 months ago that the question of DVI/HDCP inputs remained undecided. This prompted me to buy current technology.
If you're shopping now, and they announce it at CES, it is often still 3rd quarter till its available.
There are some non-xenon bulb LCOS projectors out now or soon from Hitachi and Christie Digital. The Christie vivid red will have DVI, but no HDCP. There's a thread on the Hitachi elsewhere in this section.
The higher rez DILA chip is not expected to filter down to consumer models anytime soon.
Hope this helps,
