With 'The Office' guaranteed for a ninth season, the major cast (minus Mindy Kaling) locked down, and most of the Upfront week surprises over, a ninth season for the long-running NBC comedy seems by this point completely in order.  Still, with Paul Lieberstein confirmed to step down as show-runner, what big talent just got an invitation to join, and what's still left to fill?

Deadline has announced that Dan Sterling and Brent Forrester have been tapped to come aboard 'The Office's ninth season as executive producers, hand-picked by series creator Greg Daniels.  Both previously worked with Daniels on his animated FOX comedy 'King of the Hill.'  Additionally, Forrester has served as consulting producer on 'The Office' since season 3, while Sterling most recently co-created/executive produced Sarah Silverman’s NBC comedy pilot and served as a consulting producer on the HBO's 'Girls.'

Of course, that still leaves the question of who will take over actual show-running duties, the main rumor being that Greg Daniels himself will once again ascend the throne.  With Paul Lieberstein departing to manage the upcoming Dwight Schrute spin-off, and both ratings and receptions somewhat stagnant, Daniels has been heading up a major creative overhaul for the series, which includes changes for existing characters and the introduction of new ones into the fold.

Apart from Kaling, who will leave to produce and star in her own FOX sitcom 'The Mindy Project,' all of 'The Office's main cast have been signed to return.

What say you?  Does the fact that a new show-runner for the series shake your confidence in a ninth season?  Can anyone really bring in a fresh voice, or is it time for 'The Office' to close up shop?  File your take in the comments!
