Yeah, but computer monitors at those resolutions make sense - your source material is being generated in real time by the OS. I've got a 24" at work that runs at 1920x1200, and for CAD I would be happy to have something larger still with a higher resolution. An HDTV at higher than 1920x1080 is still just scaling a 1080-line signal. Scaling can be done quite well, but its still no substitute for content at the native resolution - and if it's done badly, it can even be detrimental. That's why I doubt we'll see HDTV's past 1080p for a bit longer yet.
