If they ever do, there are a few things to consider.
1) Next year Chris will be 80. It might not stop him, but age can slow you down.
2) if they shoot any more episodes, chances are good they’ll go back to Mississippi. New York had restrictive
Union policies which made it nearly impossible to produce.
3) Nobody is lifting a finger anywhere until the virus lets up. On any tv production with puppets, you might have a few people in front of the camera, but behind it is a hundred or more. Disney had three movies in production, everything is shut down for now. Assembling actors, crew, writers, caterers, transport, etc. right now all bets are off.
