The thing is, all this gear is made for 1080p at 24 frames per second, but filmmakers like James Cameron and Peter Jackson are talking about 48 and 60fps. If I buy now, am I just going to have to buy a new system again next year, or will the standard stay viable at least long enough to get some value out of the current generation of gear?
I think the standard will remain viable for quite some time, so I'd go ahead and make the investment. Blu-ray can support 1080p 2D and 3D at 24fps as well as 1080i at 25 (European) and 30fps, but I don't know if it can do 3D with those specs. I do know it cannot support 1080p at 48 or 60fps in 2D, so it sure can't do 3D at those speeds. The entire Blu-ray specification would have to be significantly updated to allow this, which ain't gonna happen any time soon. If Cameron and/or Jackson do shoot 3D at 48 or 60fps, it will have to be "downconverted" to 24fps for Blu-ray. For this reason, I hope they choose 48, which is much easier to convert to 24 than 60 is.
