The recent UK Region B release of Metropolis includes not only the 2010 reconstructed version but also Moroder's version. I own it and can vouch for the extras listed:

The quality of Moroder's version is, IMHO, first generation VHS of a used silent-era film. As The Aluminum Falcon pointed out, the elements used in Moroder's version were far inferior.

Oh, thanks for the Info's. Seems to be a very interesting release.
