Unfortunately, I saw Hobbit 3 times in 48fps and it was absolutely mindblowing.
I could live without the 3d, but I'm not sure I want to even see or buy a 24fps bluray of it.
I confess, I don't know exactly how Bluray 3d discs work, but I thought they sent a 48fps signal to the tv with every other frame being left/right eye. If true, then couldn't they essentially use the Bluray 3d spec, but instead of 3d, just have the 48fps, then you just wouldn't use the glasses. Bam, 48fps bluray. Am I wrong?
They would need to explain on the packaging though that it requires a "3d bluray player" but you can't use the 3d glasses. Which may be quite confusing in stores for Joe Consumer, honestly. They would almost have to sell it via a special website only, which pretty much kills the idea.
I guess the best hope would be a drm'd downloadable file with 48fps.
