Here is a overview of laser development and future marked predictions from 2010 (mostly focused on the Pico marked, but it's basically the same tech just scaled up for HT PJ); Green laser diode market $500m by 2016 as pico-projector market drives growth
I believe that as soon as the despeckling are perfected, new light engine and optics designs for Laser PJ's are developed and laser prices comes down a little, both lamps and Led's will disappear from the projector marked just because lasers are both simpler and more power scalable than other light source solutions.

LED's are in a rapid state development whether it be at the hardware or projector store. The key is increased energy efficiency. 120lumen/watt is pretty sweet with even higher rates on the horizon.
I read the quoted 2010 semiconductor article. Predictions "therefore forecasts that 10–20% of projectors will be laser-based by 2011” apparently were meant for investors...

Cost and size effective laser technology has not matured at the predicted rate, probably partially due to the great recession.
There is a battle between competing technologies of lasers and LEDs. One aspect that has become clear is LEDs are not bright enough for 3D, and especially LCOS or LCD active 3D.
We are finding out that to reduce 3D ghosting, the liquid crystal must be made thinner. Unfortunately this reduces 2D contrast. At this point combination 2D/3D LCD/LCOS projectors are a compromise I'm not willing to make.
We have at least one UHP DLP projector (BenQ W7000) which has good 2D and outstanding 3D performance, with a bright and zero ghost image.
By using a process of elimination (best man left standing) everything else (either here today or hyped) is not ready for prime-time. Apparently technology is so complex that is taken BenQ engineers well over 4 months to identify and enable something as simple as 1:1 pixel mapping. Proof that front projector is all to often a pathetically backward technology.
