There are a few things missing from this collection, none of which came as huge surprise to us:
Standalone Disc Content: We have confirmed with Paramount UK that no content from the Best of Both Worlds disc nor anything from the Redemption, Unification, Chain of Command, or All Good Things discs will be included as part of this package.
While it would have been nice to include the Best of Both Worlds content in this full-series box set, it seems that Paramount UK has chosen to leave it out.
As for the other discs
well, that was always a bit of a long shot, since they were never optioned for release in the UK market at all. Youll need to buy those separately from the US, Germany, or Australia.
. . .
Best Buy Exclusive Content: This exclusive feature focusing on the Enterprise-D model, The Trek Not Taken, was included as part of Best Buys TNG Season 3 Blu-ray release, was relegated to the retailers low-quality CinemaNow streaming service.
Paramount Germany later licensed this content for their Season 4 Blu-ray release, where it was available in HD via streaming in that region.
Because of the way this content was created and financed, Paramount UK would have needed to license the feature for release in the UK market this wasnt done for the earlier releases, so were not shocked to see it missing here." - Trekcore.com
/and yeah, I'd like to have DS 9 on blu-ray as well...
