As far as I know in region 2 there is a complete TOS Blu ray set that sells for about 115 quid. The one with non remastered versions also available. But I dont know if the episodes are in production order or not.
I only have the R2 individual season sets of TOS-R which are in aired order. That in and of itself annoyed me a bit as well since the final VHS versions of TOS were released in production order on video. So I never knew why they couldnt go on the dvds in the same sequence. I still dont even know why 'The Cage' was included on the season 3 set and not the season 1.
Unless for the blatantly obvious one that it aired twenty years after the rest originally were broadcast.
