They could easily do the fresh start with CU Ash, with him going through the regions to do the leagues again. I don’t really care for Gou yet, but that’s only because their’s little information on him yet. Implanting AU Ash would result in a lot of confusion.
I REALLY hope we’re getting CU (current universe) Ash and not AU Ash. I like the AU movies, but they’re better off in the movies. I’m glad that they’re going back to a battle oriented series though, those tend to be my favorites. I do want a female companion.
