I seem to recall that right after Discovery season 2, a Pike spinoff seemed like a sure thing. Maybe not officially, at least not right away. But, there was something in the air.
There was all the talk about how the Bridge of the Enterprise was made differently. That it was steel construction and not something that would have been made for only a couple of appearance. It was built for a higher purpose than just a couple guests appearances.
Anson Mount, Ethan Peck, and Rebecca Romijn talked about the possibility of a spinoff in an almost teasing fashion, barely containing their glee.... like they knew.
Plus, Paramount was spending money like drunken sailors. Strange New Worlds was pretty much a sure-thing, long before any petitions even started.
At least that's my read of it.
I'm not getting that feeling this time. Yes, there's the petition and a very vocal group of fans, but that's it.
It's pretty much radio silences from Paramount. The cast and crew certainly aren't gleefully teasing a spinoff. Hell, some of them seem like they're begging for work. The sets were all destroyed, save for the Ent-D. Matalas is working on other projects, and Paramount is in the process of cutting cost.
If Star Trek: Legacy has any momentum, it's moving at a glacial pace.
