Why are there moving black bars on the sides of some 3D discs?

If they're smart, they'll just package the separate 2D version with the 3D version, as Disney will be doing with A Christmas Carol.

It's not like the studios wont be producing 2D BDs of these films, that's where 99.9999% of their Blu-ray sales will be coming from.
