It is not a different 3D. It is Sky's way of creating some marketing leverage. The Sky article mentions a prototype which may not be offered to subscribers. It refers to delivering to one of the screens which replaces the need to wear 3D glasses. These screens will not be in households in 6 months time, because at the beginning of the product life cycle they will cost far more than £2K.
Lets face it, many people do not know the difference between HD ready and Full HDTV's, Plasma vs LCDs and so on. Many people still don't know what Blu-Ray is let alone venture into the realm of exciting 3D possibilities.
The article refers to a "new grammar", but there is nothing new in it. The British film makers Bob Angell and Arthur Wooster have been shooting this way since the 50s.
Panasonic has some interesting developments with the P2 HD broadcast camera (small, compact, twin lens HD system), but one still requires the 3D glasses with the 3D-ready Plasma TV. Westfield London has a demonstration between 8-13 Dec of the 3D TVs I believe. It should be exciting to attend just to see what is going on and as I live close by I will check it out.

Thanks for the interesting article from techradar.com and the comments from vikinger - on still images without special glasses/screen - I will check them out.
