Who else? I haven't heard.
Mindy Kaling and BJ Novak are working on a new show called "It's Messy," (about a young female Doctor) and as you mentioned Paul Leberstien is leaving to write and work on Dwight's new show. So that's at least 5. (6 if you count Carrell who is already gone). Wouldn't surprise me if Jon K & Jenna Fischer didn't renew their contracts.
