This seems insane instead of just making it a December 2026 release. Disney has nothing coming out that December. Oh, except they do now because there's supposedly two Star Wars Movies coming out in 2026 which seems like a bad idea. December 2026 and 2027 are earmarked for Star Wars. It's either going to be the Mangold movie in December 2026 and Filoni in 2027 or vice-versa.
For context, May 22, 2026 for New Jedi Council is only 3 weeks after Kang Dynasty. The Last time a Star Wars movie released in May, it was Solo: A Star Wars Story, only a few weeks after Infinity War.
