Given that no one has propsed a home-theatre spec using 4:4:4 12-bit video... and most people don't have easy access to dual-link HD-SDI connections anyway... I wouldn't bet on being able to use D-Cinema presentations anywhere but the cinema any time soon.

I just checked the hard drives for BEOWULF 3D and the movie and audio occupies 176.8Gb. You also have to remember that this also runs at 144FPS (72FPS left eye and 72FPS right eye). To get that high frame rate for the the 3D, the resolution is usually brought below 2k.
I have not seen too many of our digital presentations at my theatre run over 300Gb if any.
