Gonk:
You are probably right about the 3D, I had forgotten about that.
On the resolution front, Samsung is currently selling a 23 inch monitor with 2048x1152 for under $250 retail. Using the same glass would produce a 46" monitor with 4096 x 2304 so 2160 in my mind is a very reasonable next jump. I could sse a basic monitor at under $1000. Throw in mulitple tuners, other electronics and scaling firmware and a solution in the $3K range seems reasonable. They could even offer picture in picture with 4 1080p hd images.
