Yeah they seem to be largely inactive these days and just working on distributing and remastering some of those valuable properties thats probably why Debbie Allen cant get anything off the ground but I think you are right they might be able to do it without him.

Yup. I mean he's not necessary. Truth be told, legally, he's got no ties to it. He created none of the characters, he had an executive producer credit ( I think) and outside of the music, that's all he had a created by credit for. So whatever issues she was dealing with 3 years ago, that's probably that. The reason why things like Full House can continue or things like boy meets world is because its the producers of the show going to these companies and offering them something, not the other way around. Debbie Allen and the producers would need to go to NBC or Netflix and pitch it to them. A different world just hit netflix recently and a lot of their other shows are on there so clearly they have a good relationship with Carsey-Warner so for all we know, maybe something is going down now
