Right now Trek exists in three eras (in universe):
- 22nd Century - Archer's era
- 23rd Century - Kirk's era
- 24th Century - Picard's era
So one logical place for a new series to be set has always been the 25th century - the next next generation. But although we fans know Star Trek is a big enough setting to have brand new crews, it seems like the studios think of Star Trek in terms of TOS being a core property around which other things are spun off.
- 22nd Century - Archer's era
- - Enterprise
- 23rd Century - Kirk's era
- - Discovery
- - The Original Series
- - The Animated Series
- - STAR TREK: Phase Two (CGI series)
- 24th Century - Picard's era
- - The Next Generation
- - Deep Space Nine
- - Voyager
- 25th Century
- - STAR TREK: The New Adventures
- - STAR TREK: Challenger/Pioneer
If that's the case, an animated CGI series covering Kirk's lost 5-mission on the Motion Picture refit would make perfect sense - no need for Shatner, Nimoy, Kelley.
But I'm worried about this trend of making things that are really closely linked to the existing shows - like a Khan spinoff could be the exact sort of uneccecary fanwank other franchises churn out if handled poorly - and a Picard return could likewise be awful (optimistically it's retired Picard going on an archaeological adventure for 50 episodes - but knowing Hollywood it would be "let's trot out the Borg, ruin them further"). So a super expanded list could end up looking more like this - and if it was a perfect world and they were handled well, I wouldn't mind:
- 21st Century
- - STAR TREK: Year One
- 22nd Century - Archer's era
- - STAR TREK: The Kzin War
- - Enterprise
- - STAR TREK: The Romulan War
- 23rd Century - Kirk's era
- - Discovery
- - The Original Series
- - The Animated Series
- - STAR TREK: Phase Two (CGI series)
- - STAR TREK: Khan's Inferno
- 24th Century - Picard's era
- - The Next Generation
- - Deep Space Nine
- - Voyager
- - STAR TREK: Immemorial (Picard the Archaeologist)
- - STAR TREK: Klingon Defence Force
- 25th Century
- - STAR TREK: The New Adventures
- - STAR TREK: Challenger/Pioneer
They could expand in any direction in the 25th Century - have the Dominion return with Odo as it's emissary - be challenged by hereto unknown civilizations, even from beyond the galaxy. But I think it would be a good idea to have an optimistic core show to re-establish the brand before doing anything crazy - and space should feel like a marvel again.
I really don't know if Alex Kurtzman or Akiva Goldsman is the right person for this, it's beginning to look like Seth MacFarlane might have been a good choice for the 25th century optimistic core show, but if they dish it out to like three different teams that could be great.
