Nope. Not happening. Not now, not ever. That ship sailed with Nemesis atrocious performance.I'll just keep wishing for a sudden announcement of a new Prime movie, set in the TNG/post-TNG era, starring Sir Patrick Stewart, Mr. Brooks, Mr. Dorn...... ahhhh one can hope.
I'd be surprised if ST4 is the last "Kelvin-verse" movie, but I can see doing a spinoff series based on a new character - say a series with Sulu and the Excelsior and closing the book on Kirk and the Enterprise.ST4 will, from what I hear, be the final Kelvin-verse film. So it's a very open-ended question as to which universe any subsequent films (if there ever are any) would involve.
I can imagine that if DSC has a successful run, they might do a TV movie to close out any open plot-lines, like Ark of Truth did for Stargate SG1. A feature film based on the "Discovery universe" is unlikely until Paramount decides they're done with Kelvin movies altogether.
