Not gonna happen. Ask CAVX or the other lens guys how costly it is to make decent lenses. Prisms are cheap, but their quality leaves a lot to be desired. Plus they are bulky.
What I think is much more likely is that the market will eventually shift entirely over to laser projectors that have no optical elements and thus are focus-free, and can alter their beam / zoom to any arbitrary aspect ratio, like an old CRT you could adjust the height and width of the electron beams independently. That way you don't need lenses at all (anamorphic or not). You could even alter the aspect ratio in software. Let's say you detect an incoming signal of 2560x1080 or 1920x810 (say, letterbox Blurays) instead of 1920x1080, the projector could automatically either cut off the letterbox scanlines, or scale up to 1920x1080 vertically then scale back down to 2.37:1, or if given 2560x1080 it could scale it down internally to 1920x1080 but then stretch it back out by expanding the laser beam dispersion. (or scale it down vertically, which gives the same result, except a change in zoom).
My prediction is that pico projectors, once they can get their lumens up, will destroy the traditional projector market, at least in the consumer space. Low persistence, low blur, perfect blacks, great colors, no focus, perfectly quiet, portable, low cost, wireless, eco-friendly...you could even adjust the geometry to align the laser beams to perfectly fit your screen from a wide variety of angles, doing effectively perfect keystone correction in software. At that point you could even put markers or lights on your wall, and have the projector realign its beams in realtime so you could hold the pico projector in your hands as you walk across the room, and it could automatically adjust itself on the fly to keep projecting into the target screen area. Now that would be a neat trick, wouldn't it. Just need a camera in the projector to see the markers on the wall or even do some image recognition on the rectangle of your screen and then re-spec its internal corner points in 3D space accordingly. The maths behind that are fairly straightforward high school stuff.
