Not heard anything since the initial announcement, and he's still listed on Memory Alpha and IMDB. Not that that proves anything, but it suggests there has been no release contradicting it.
Menosky's history on Trek is a roller-coaster. Darmok, Distant Origin and Scorpion, but also Interface, Masks and Times Orphan.
I'd be very happy if he was still on the team.
As a distinct detractor of the show, looking back at his VOY input, many of his episodes would land on the "would re-watch" list and some of them are straight up great. Similarly, on his TNG days barring
Legacy, Interface and
Emergence, most of them are top draw and/or creatively adept.
Along with Braga in his early years, Menosky always appeared to offer up a few of the more wierd and interesting ideas -
Masks (which is so insane I love it),
The Thaw (another love/loathe episode that I adore),
Darmok (Top end TV),
Dramatis Personae,
Distant Voices, In Theory, The Nth Degree, Distant Origin
On top of that he significant hands in many of the "big" episodes, be them adventure or thoughtful kind:
I, Borg, The Chase, The Killing Game, Year of Hell, Future's End, Blink of an Eye, Living Witness
I'd actually say he was one of the saving graces of VOY
In fact the more I look at his resume the more I wonder how he's not moved up to Showrunner or similar. He has a strong writing voice, seems apt at experimenting with episode structures/ideas and can flit between the grand and the personal.
If he's on the team he's the most exciting part of the production.
If not, I hope he lands somewhere soon. In fact, Braga's show
Salem, just hit Netflix and Menosky was a writer there. Might check out his stuff.
Hugo - yet
another show to put in the queue
