What exactly then, is this thread about? If no one cares about the show maintaining consistency with the rest of Star Trek, what does it matter which timeline it's set in?
They could set the show in 2017, slap Star Trek in the title. Have people walking around with Samsung tricorders and driving Corvettes into shuttles. Only fanboys care about the details like dates and ship dimensions.
Fair enough... though its existence does render quite a few crisis in other scenarios of Star Trek moot. Anyway... these things have been argued endlessly already.
There's always been three choices for a timeline. Prime Universe, Alternate Universe and a third timeline.
There's good reason why Alex Kurtzman would develop the show to be set in the alternate timeline created in the 2009 film. He is 1/3 or 1/4 of the creative force behind it. No one would blame him for setting the show in that same timeline... but to what end?
Paramount wants a 4th and possibly even a 5th Star Trek film with Chris Pine and Co, if reported contract agreements are to be believed. That means any new show set in or around the events of Star Trek/STiD would require a lot of synergy and communication between the TV and Film side.
Agents of Shield/MCU is a great example of how awkward and constraining it is to do that even if it's planned from the get-go.
So if it's set in the JJ-verse, it'd have to be either a pre-quel... which is in the prime-verse... or a sequel... which would lead to even more conflicts with the prime-universe.
When they decided to do Into Darkness they were pestered with the question, "When are you guys gonna do Khan?" over and over... and over again. And they decided to do Khan, only not quite the same Khan with these "echoes of the story" elements. ...and it was largely derided as a "TWoK" rip-off.
Imagine them dealing with that for the entire series... comparing it to the ToS-movies era or the TNG era of whenever they decide to set it in the JJ-verse.
Any homage they decide to pay to great moments in Star Trek will be called rip-offs. Anytime they do something vastly different they'll get accused of shredding canon by fanboys like me.
Instead... why not just go... a little bit beyond the primeverse? Set it after Star Trek: Online... or post-Hobus Supernova... There is a good reason why this might be the case.
Leslie Moonves, who historically has HATED Star Trek production at Paramount, considering it a low-ratings waste from 2000-2006 now says this:
"All the series have done well in terms of streaming... Added in to that, Star Trek is a huge international franchise. Our international distribution guy is going crazy; he can't wait to get out to the marketplace and sell that. Right away, we're more than halfway home on the cost of the show from international alone. The risk is small in seeing the track record. We think it'll be great and bring in a lot more subscribers. We're really excited about it."
Leslie Moonves is a shrewd businessman. When Nielson ratings of Voyager and Enterprise were low, he thought of Star Trek contemptuously. Now that streaming is the absolute future of television, Star Trek looks like a sparkling diamond.
It's not 4 hours of Star Trek (2009) and Star Trek Into Darkness that people all over the world are streaming. It's 700+ hours of a library of 5 television shows that people are falling (obsessively and fanboyishly) in love with.
They're falling in love with Kirk and Spock, Shatner and Nimoy. Picard and Riker, Data and Worf. Janeway and Seven of Nine. Bashir and O'Brien... and hell, even Trip and T'Pol. Wouldn't it be nice to go back to that playground where all of these beloved characters are? Isn't that what we all want?
What better way to make money than to give fans what they want? I think it's a good bet that the new show takes place beyond the TNG era...
