For the benefit of the few fans who haven't read the Comic Con coverage on other sites, I think there's at least one or two out there, here are a few bullet points from the Community panel about the upcoming Season Four:
- New showrunners Moses Port and David Guarascio reassured fans that they won't screw things up
- New relationships among the main characters will be formed, Jeff and Dean are singled out as a possibilty
- There may be animation in the season premiere
- The study group will go to an Inspector Spacetime convention.
- Pierce's mansion will make an appearance and we will get to know more about his private life
- Jeff Winger's father, William Winger, will finally appear.
