Mitsubishi has announced to show a Laser-TV prototype at CES-2008. Maybe we see also some product roadmap.
But it does however seem to exist in some form now. Laser TV is a projector TV technology that uses lasers instead of incandescent lamps to create light. Proponents say it uses less power and allows for lighter sets than even LCD displays offer, with "bulbs" that never burn out. True? We'll see soon: Mitsubishi has sent fancy invitations to a big unveiling of the technology at the show already, and I've got one in my hot little hands. Say tuned.

OLED TV - The sketchiest TV technology of them all, OLEDs, or organic LEDs, have found only minimal adoption in the industry so far, and primarily in tiny applications like MP3 player and camera displays. OLEDs are attractive because they don't require a backlight, unlike all other display technologies, which means they are very energy friendly and (eventually) affordable. Last year a 27-inch prototype was on display by Sony, and the company launched the set commercially in Japan a month ago.
Are bigger sets on tap? No one's saying... yet.

SED TV - Another long-suffering TV technology, SED (Surface-conduction Electron-emitter Display) is another LCD competitor with similar design, but this one has been in the works for about 20 years with little to show. Prototypes were shown in 2006, then none in 2007. A few announcements have emerged in recent months, but nothing concrete. Whether SED appears at all this year or not is a mystery.
