Considering it's the 40th anniversary of Return of the Jedi, I think Leia Organa being a Rebel-centered GL would make the most sense. For next year, I'd expect GLs of Ahsoka and/or Thrawn once people have had the chance to take in the show and its contents. With all of the live action Disney Plus stuff we're getting, I would imagine a Thrawn GL could lead an improved Imperial Remnant, and Ahsoka could lead either Unaligned Force Users or else maybe a New Republic tag that I'm sure will be incoming sooner or later.
But for this year, I would be very surprised if it was anyone other than Leia Organa from Return of the Jedi. Just my two credits.
