I also saw the Click article over the weekend and was interested to see what was going on. The BBC R&D department has a history of inovation years ahead of it's time with things like Nicam, Teletext and Freeview. Even through super HD is probably 10 years away for consumers, there has to be content available when it launches and the broadcasters need to have equipment and systems in place and know how to use it. From what I've read elsewhere, the camera technology has been available for a while now, just not really put to use as there's no way to watch it!
That all said, I think it's a shame that the BBC only provides one limited channel output in 720 HD and yet is happy to promote things like this and 3D TV already. I get the feeling this was more of a publicity stunt that just happened to conicide with Sky launching it's 3D service.
As for the screen technology, I remember seeing the first demos of HD TV on Tomorrows World in the 80's, and that was on BIG CRT's at the time. In the Click article they mentioned that for resolution alone, there aren't any screens available to display the full quality image yet. Technology moves a lot faster these days and they will come. My 3 year old "state of the art" 1080p 100hz TV is testament to that.....
