Yahoo Bows 'Community's' Sixth-Season Trailer

But no word yet on whether the Dan Harmon comedy is in its final season.

Greendale Community College is back in session.

On Tuesday Yahoo released the trailer for the sixth season of Dan Harmon's cult comedy series Community.

While Yahoo is using the tagline: "Class uncancelled." there's still no official word on whether this season of the Joel McHale starrer will be its last.

Yahoo Screen revived the series when NBC canceled the comedy after a low-rated five-season run. This season saw former star Yvette Nicole Brown exit to care for her father and, with pilot season in full swing, has seen castmembers Ken Jeong (ABC's Dr. Ken) and Danny Pudi (NBC's Strange Calls) also sign on to new projects in first position, which would require them to sign new contracts should Yahoo opt to bring back the series from Sony Pictures Television for a seventh run.

Meanwhile, season six will feature new additions including Paget Brewster and Keith David.

Watch the new trailer below. Community premieres March 17 on Yahoo.
