I don't feel like 101DS would be get cancelled or experience some budget cuts. 101DS has a decent fanbase, and it's doing pretty well on Disney+. I think 101DS would become a Disney+ exclusive in the UK/ Europe, and will release new episodes every few weeks. But when the season is completed, it'll be released to the rest of the world. Or they might just make it a Disney+ exclusive like, "High School Musical, The Musical, the series" and "The Mandalorian", and release new episodes every few weeks for the world to see at the same time.
I am honestly think during this decade or by the end of it, Disney channel would be all on Disney+.
