SNW had Akiva Goldsman in it's corner. He was pushing for it from second he was hired.
It has Terry Matalas & Fans pushing for it.
Strange New Worlds had a lot more going for it.
It had Akiva Goldsman champing at the bit to get it made. It had a partly created Bridge set already constructed in Toronto. It also started production during a much more stable period for Paramount Plus. It had the momentum.
The USS Titan / Enterprise Bridge is already built, same with other parts of the ship.
As far as Paramount Plus status, that's a different story.
What momentum has "Legacy" got left? Its supposed showrunner has his hands full for the next several years. Nothing is built. And Paramount only has so much money to throw around.
You saw PIC S3, a good chunk of the Ships sets were already built.
Money is the biggest issue.
Most of the casting is figured out.
Deep Space Nine seems popular too. Don't see it getting more made at the moment.
Part of the problem is many of the cast is retired, passed away, or aged out of playing the role.
Sadly that's been a big issue with DS9.
Avery Brooks is retired and not acting.
Rene Auberjonois has passed away
Aron Eisenberg has passed away
Marc Alaimo has passed away
Louise Fletcher has passed away
etc.
And alot of the existing DS9 Actors have shown back up in Lower Decks.
