The "something disruptive" may be high frame rate and high resolution 3D.
This is from the webpage http://www.hfrmovies.com/high-frame-...xample-videos/
Polish production company FlyFilm
has created a great demonstration video showcasing variable frame rates. The frame rate in the below video is 50 fps during fast action, and is 25 fps (still playing the 50 fps file, but dropping every other frame) when the onscreen movement slows down.
The below archive contains left and right eye video feeds, and can be viewed in stereoscopic 3D with Stereoscopic Player

I generally prefer Bino
to Stereoscopic player. If you set your desktop to 50p and play the left and right files of the Flyfilm demo as a stereoscopic pair, the superiority of 50p over 25p will be quite apparent. For 2D it doesn't seem to matter as much. For 3D, a high frame rate is very beneficial. Peter Jackson made the right decision with the Hobbit
movies to use 48fps for the 3D, but naysayers* jumped on him for doing so. With care, 24fps 3D can work, but it requires very slow pans and generally slow action. In Avatar,
there is a scene early in the film where the commander addresses the new recruits. As he walks in to give his speech, only his boots can be seen, moving across the floor. There is a strobing effect as the movement of the boots is too fast for 24fps and 3D. Had James Cameron been permitted to use 48fps or 60fps, the boots would have stayed intact visually when viewed in 3D.
The other factor is resolution. Human eyes need fine detail to process 3D parallax. Attempting to broadcast the London Olympic games in 3D with half side by side 1920x1080i50 was a flop in the UK. The i50 was not as good as p50 would have been if technically feasible. And the 960 + 960 pixels for Left and Right compromised the horizontal resolution.
In the US, sport at half height 1280x720p60, or half width 1920x1080i60 has not been ideal.
A further factor is the timing discrepancy introduced by shutter glasses. Perhaps OLED will allow higher alternation rates. I find the timing discrepancy from shutter glasses operating at 100Hz for a 50p source hard to tolerate. I find the usual 120Hz shutter glasses rate for a 60p or 24p source tolerable, and the 144Hz of RealD cinema smoother again. I suspect 240Hz would be a good rate to aim for, allowing a double flash of left and right for a 60p 3D source, i.e. LRLR for each frame.
I believe that unless and until frame rate and resolution are addressed, even glasses-free 3D would not appeal to many viewers for watching sport on TV. The lack of temporal and spatial detail would cause frustration.
Passive 3D 4K sets immediately overcome the timing discrepancy issue as the timing discrepancy between Left and Right with passive 3D sets is nil. We are still in need of high frame rate 3D source material. This is also tied up with the need for video codecs that are more efficient and graphics cards that can provide hardware acceleration at high frame rates and high resolution for 3D. (There is a big jump in pixel rate going from Full HD 3D at 24fps and Full HD 3D at 60fps. And attempting this at 4k instead of Full HD will require a further 4 fold increase in pixel rate.)
* The media love to report negatively. And people love to read about failure. The handful of people I know who saw either of the two Hobbit movies released so far had no issue with the 48fps 3D. I relished it myself: beautifully fluid. The reporting concentrated on the negative impressions of some moviegoers, and pretty much ignored the positive impressions of other moviegoers. It will be interesting in 10 or 20 years to look back at this era of the transition from 24fps to higher frame rates, even for 2D. 4k will be a catalyst for a change to higher frame rates. 4k at 24fps even for 2D creates extremely obvious panning jitter/judder and blurring, defeating the otherwise high resolution of 4k.
