1) Yeah, I absolutely knew Trek would come back on television one day - it's simply too big a property at this point to ever die, as long as we will have hour-long live-action entertainment, Star Trek is probably going to be present in one form or another. How successfull, and how long the hiatus inbetween, that's a completely different thing.
2) I absolutely did not forsee an entire new streaming service basically banking it's entire existence on Trek, nor that so many shows would be produced at the same time without the property showing big mainstream success for a while again. I would be much more confident if DIS would already have run successfully for a few seasons. But it seems they are heavily reworking the entire approach of the show for the second season - and at the same time shelling new products out as if their life depends on it (the life of "All Access probably does...).
So I'm cautious. They are banking a lot on people blindly paying for everything with "Star Trek" in it's name. And if the majority of shows is actually good that can completely work. But if the quality simply isn't there - and so far they really haven't shown it to the degree necessary - , they can run out of steam super fast as well. It would really be a shame if the new surge of Star Trek shows walks into the same fate as the Marvel Netflix shows in 2 or 3 years...
