They've billed it as Star Trek: Picard.
God willing, if they do a follow-up to Picard set on the E-G, they're going to give the show another name entirely (much in the same manner that Better Call Saul is a spin-off of Breaking Bad).
If Jean-Luc is not going to appear in this follow-up series, why would they continue to preface it with Star Trek: Picard?
Seven of Nine has had a salivating fandom for over twenty-five years. She doesn't need Jean-Luc's pixie dust any more (if she ever did).
