They already went to the well too often with all this. It's funny because I rewatched Fellowship last week and marveled at how well it was done, thinking that there would never be a need to make those books into film again.
But I didn't think through the idea that they could beat this dead horse into oblivion with unnecessary prequels, sequels, and spin-offs. If they are going that route, it would be better to bring on new people with fresh ideas instead of rehashing what you did 25 years ago with the same people.
You never know, but I'm not holding out much hope for this.
