Go with a reasonably priced 1080p set with a nice response and contrast ratio. Several future display tech's will allow for lower cost larger screens, less energy consuming, longer product lifespan, and ultra-ridiculous contrast ratios. So keep that in mind when making your purchase, the resolution might not improve but other factors will.
Personally I'm waiting for projectors with the next-gen LED lamps that have ultra-long lifespans and low energy consumption, that will give the largest possible screen for the least space, price and energy consumption combination. After that touchscreen enabled HD color electronic wallpaper which does not consume energy unless the image is changed or goes into video mode.
With my walls roof and floor covered in HD touchscreen enabled color video capable e-paper wired to my computer, and some adequate software I will be able to pop-up multiple monitors, tvs, etc, expand and move such around with my fingers, put dynamic moving images of forests, clouds, etc. on the walls.
Move pictures, and painting from one area to another, from wall to wall, from room to room, even to the roof or floor. I'll also be able to expand and contract sizes of such, and of multiple tv windows, and be able to have my desktop running on the wall, and expand, contract, and move windows around the house.
Yeah, that would make even Great Bill's once state of the art 100+M house seem like something out of the stone age. But that my friends is the power of technology, in the coming decades we will have available at a reasonable cost tech that surpasses even today's 100+M homes of the super rich. Of course the common man's home land area won't be that big for a while
