There was a news piece very recently about this and apparently because of the cost of the equipment necessary many '3D' films will have the effects added (or fiddled about with) in the post-production stage.
Rather like HD, programmes made specifically for the medium will always look best in it.
The opinion was also expressed that gaming was indeed the likely way forward (in the near term) for this technology.
Unless the whole film is treated as a CGI creation, the live action has to be shot in stereoscope which is quite complicated to get right. As soon as you add visual bits in post-production it gets quite hairy as it is possible to create invalid perspectives that do people's heads in.
The down side is increased cost of production just when no-one has any money. The up side() is that you might put your competitors out of business and get the whole arena to yourself.
As it is, manufacturers are putting resources into making their equipment capable of producing the stuff and may never get their money back, or could even go to the wall.
My verdict is that if mainstream tv production companies keep chasing this fantasy, our tv programme quality will drop still further and we may be back to three channels.
That's the very point they were discussing Chris but I have to say that the cameras shown were impressive looking to say the least.
I do agree with you about what may well be misplaced faith in the technology and how doubtful it is (in my view anyway) that technology can make a poorly produced, misconceived or ultimately unwatchable programme morph into something desirable.
With Sky HD, Freesat, Freeview and a Technomate 6800 HD which runs through a Unicorn 1.2 reference dish I suppose I could watch about 2 thousand channels - encrypted/unencrypted - from various providers however I find myself regularly watching 6 or so video channels and listening to a few radio ones.
So you may well be correct - excessive choice while having a certain allure, becomes less urgent when that choice serves up little but dross, and the more that broadcasters and service providers try to saturate the market by this using scatter-gun approach the more likely it is, perhaps, that things will go teats-up with subscribers ending up confused, stupefied and entirely mystified by the whole shebang.
Should it not be for Sky Arts, Jazz FM R3 R4 (sat. delivered) Sky1 BBC4 ITV4 some news channels, (especially Sky to see Alex Crawford, Kay Burley and Sarah Hughes) and the odd delve into Universal - I would have nothing to watch or listen to.
