Sigh. Maybe, it all depends on what I see from the previews or something from "Legacy". All lot of things would have to happen for me to get invested. The ship designs have to look pretty and not what I've seen so far, and the uniforms needs a new touch where it has the Star Trek DNA but is not similar to TNG. I would like the stories to be ship based along with the characters and not another Galaxy wide super threat, I'd hope for tales which are not serialized. Probably not going to happen but we'll see.
I'll never watch STRANGE it is not a prequel to the CAGE or TOS and there's nothing I noticed that could draw me in ever. I read too many things that leaves me cold.
You're right about a possible new series with Seven but the Titan design to me doesn't deserve the name Enterprise. Sorry I was never a fan of the ship designs for CBSALLACCESS + Trek.
I really like Sidney La Forge and I hope she's cast for the Legacy show, I think I could be invested in seeing that character as a regular on that show, but a lot of things have to happen in order for me to watch.
For me, I would like the franchise to move on from TNG timelines and move forward into the future where there's a clean slate. The DNA is still there but brings something new... I miss explorations from a ship and doesn't drown itself with LEFTIST politics, like the Anson Mount show, but tell a neutral story where I can understand both sides of the issues and not feel attacked because on my conservative views. I can only be optimistic for what comes but I am glad to see my heroes once more and the Enterprise in PICARD.
