My guess: theoriginal release date was positioned to keep some distance fromShang-Chi. At a glance both martial arts heavy movies might feel too similar to casual audiences. But then Shang Chi moved from July to September. The holiday season is gonna be crowded enough with Eternals, Spider-Man 3, and Venom 2. So pushing Snake Eyes closer to the holidays risked it getting lost amongst that competition and other family focused holiday and awards movies.
So if they couldnt keep far enough away from Shang-Chi they might as well get out first. Its gonna be interesting to see what trailer drops first, how people respond to both, and if buzz strongly favors one over the other.
And here we all thought Snake-Eyes nemesis was Storm Shadow...
Maybe Hasbro strong armed them into movingup Snake Eyes so they could sell the movie merchandise.
Cool to see Snake Eyes moved up, but Top Gun Maverick being pushed back is a bummer
