From MovieWeb:
“What is fun about this is, in many ways, I don’t think it feels different than working on a movie. It certainly doesn’t feel like we are making any compromises. It’s the same creative conditions in every department to do what we can do. We also have this backlog of characters. A lot of the characters that we built for all of the films either didn’t make it to the final cut, because that’s just the way that the film process happens, or that they are seen so momentarily that there is this wonderful second opportunity to bring back some of the characters that we’ve made and bring them to this new storyline in a more, shall we say, integrated way. I think it’s going to be tremendous. I find that it’s a second opportunity for everything that we’ve made, plus the opportunity of moving TV along, in a sense, at what will not at all be diminished as far as the level of quality, the level of things that we are going to try and achieve.”

Makes sense really, especially since they’ve already worked on this era, I’m sure there are plenty of unused concept art, alien costumes, animatronics and puppets that they can just pull out of storage and add to the series. The RO aliens were IMO the most OT-like designs we’ve gotten so far with the Disney movies, so it’s nice to see that these “old” designs are going to be re-purposed.
