SDCC gets Community…animated episode to be announced?

The future of Community has literally turned around 180 degrees in just a few weeks, as we once thought the series was dead, but we now know will be getting new life on Yahoo TV. What we don’t know yet is what kind of animated episode we can expect for season six, so hopefully we can get some clarification on that at San Diego Comic Con, though the press release doesn’t really give us much at this juncture:
Community (Yahoo Screen) TV Guide Magazine presents: Greendale Forever, a Tribute to Community. EPs Dan Harmon and Chris McKenna will be joined by the cast. 2:15 p.m., Ballroom 20.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
