2022 makes perfect sense because the Fox deal finalized in 2019. The 40th was skipped for Star Wars but celebrated for Empire and Jedi which Disney had the rights to. So the 50th anniversary is kind of a big deal, even more so being the original.

Nothing of this magnitude has happened since the 1997 Special Edition, and the original Star Wars hasn’t been seen since the 1980 reissue. 1981 being the year A New Hope was added and they redid the crawl and starfield.

In 2027 it will have been almost 46 years since anyone has seen the original cut of Star Wars. As of this year it has been withheld for 44 years.
