Although there hasn't been any official word yet from Paramount regarding a Star Trek: Picard spinoff, the Star Trek: Picard series finale definitely set up enough loose ends for multiple possible spinoff series in the future.

For example, Ed Speelers's Star Trek: Picard character Crusher (i.e., Captain Picard's son) could definitely star in his own spinoff series.

Other characters in Star Trek: Picard, like Captain Worf (Michael Dorn) and Beverly Crusher (Gates McFadden), were also left with fates wide open, with plenty of opportunities for them to explore space in new stories yet to be created Star Trek: Picard spinoffs. There was certainly plenty of potential with a lot of old and new characters introduced in Star Trek: Picard.

(Also — give LeVar Burton his own Star Trek: Picard spinoff already!)
