There was "Metropolis: Morodered", and I believe that one is an LD transfer of the original Moroder version. I don't have that one.
However, I do have a copy of the "Metropolis Redux" version. The benefit of the Redux was that it colorized the early 2000's restoration, so there was better definition than the Moroder bootlegs flying around.
Now owning a copy of the 2010 reconstruction on blu-ray (and looking to get another region's release for the sake of completeness, in terms of extras), I'd be curious to see if the colour could be lifted and applied to the high-resolution blu-ray transfer with minimal effort. Judging by the disc's creator's elaboration on his method... I'm guessing it would be a considerable effort.
