The Robot Carnival DVD is available....
The Robot Carnival DVD is available at animespectum.com, or more specifically, http://www.animespectrum.com/anime-dvd-r-robot-carnival.html
I just ordered mine for $15.83 with shipping. This is the original version, imported, with english subtitles in the options. 7 of the 9 shorts on this DVD don't have any dialogue anyway, so the language thing for those who insist on waiting for an English dubbed re-release, shouldn't be too bothered by it.
