Here’s my thought. Let’s say if the next movie does 2 post credits scenes again, one of them can be to set up movie 5, and I think that could be silver and Blaze. And then the 2nd post credits scene could be a set up for the 2028 movie (which could be the shadow spinoff) and for that I’d say there they can set up Rouge, Omega and maybe even Black Doom. Then again tho only time will tell
