So just who is back for Community: Season 6? There’s been some fan concern about which cast members were returning to the show, when new episodes debut on Yahoo and Uproxx noted that there was some questions regarding Alison Brie’s participation in particular. Recently, Community writer Ryan Ridley had responded on Twitter to a question about whether Brie's character, Annie, was in the script for the season premiere with “Not sure yet" and the actress hadn’t mentioned the series on her Twitter feed since NBC cancelled it, including when Yahoo saved it a few weeks later at the last minute

The rumor about Alison Brie not returning is utterly, 100 percent false. I'd add a joke but I don't want to be unclear. She's coming back! — Dan Harmon (@danharmon) September 10, 2014

IGN has checked with sources close to the series and can confirm this: Alison Brie is under contract for Season 6, along with Joel McHale, Yvette Nicole Brown, Gillian Jacobs, Danny Pudi, Ken Jeong and Jim Rash. All seven of these actors are expected to be a part of the new season. Now keep in mind we don’t know if this means that they’ll all be in all 13 episodes, but you should expect to see Jeff, Shirley, Annie, Britta, Abed, Chang and the Dean again in these new episodes.As for Jonathan Banks and John Oliver, while they had significant roles in Season 5, they both were technically guest actors and not under contract. With both of them much busier these days – Banks with Better Call Saul, Oliver with his HBO series – their participation in Season 6 remains to be determined.Community Dan Harmon has now tweeted the following, making things even more clear.
