Also, where are you getting numbers like 10 and three from for heyday and current...?
Here's the list of Disney TV shows. There are more than a dozen current animated on-going (or "not cancelled") shows! The list needs updating, but Clubhouse, P&F, Fish Hooks, Gravity Falls, Jake, Sofia, McStuffins and Wander all seem to still be alive. And that's eight.
At least, because there also things like Bow Toons (short), Spider-man (maybe on-going), etc.
