I can't see any future in it.
In fact I can't see any future in ANY of the TV formats that are proprietary non open and require manufacturers (and presumably producers, broadcasters, etc.) to pay licensing fees for.
Can you imagine the situation if we had the BBC broadcasting in one format and ITV in another? Even the French had to give up SECAM and the PAL / NTSC formats have gone the way of the Squariel in the days of digital broadcasting and streaming.
