Region 2:
Europe, Japan, the Middle East, Egypt, South Africa, Greenland

Region 2 has both the single episode DVD and the Season 6 box set now available. The single disc appears to be an English language version of the earlier German disc, with the notable exception of having Dolby Digital 5.1 sound (at least that was the info on Amazon before its release, it doesn't specify that now, so I'm not sure if that's accurate.) Apparently the Season 6 box set was originally scheduled for April, but was pushed back a month to release the single disc first.

If you're not planning to buy the full Season 6, this is the one for you.

You can order the disc through Amazon.co.uk.
