Yup, Ryan did get that promotion on The Office
Remember the twist at the end of the season finale for The Office, where Ryan got the job that Michael, Jim, and Karen interviewed for? Judging from e-mails and other comments, many fans were confused and didn't think that Ryan really got the job, that it was some sort of trick out by the show that would be explained when the new season starts. But it looks like Ryan did indeed get the gig (which is probably good, since it would be weird being in the same office as the girlfriend you just said "we're done" to).
At the end of this New York piece about new NBC head Ben Silverman, it is revealed that B.J. Novak (who plays Ryan) will use Silverman as an inspiration in his new job. He's even studying his mannerisms.
The article is a bit confusing in its own right though. It says that Ryan is "the newly made boss on The Office," which makes it sounds like he got Michael's job.
