People sleeping in-house for a media client that isn't released? Or having A-class issues? Highly unlikely.
If any of Apple's projects has in-house living requirements, it would be Maps over iTunes. itunes does have the "announcement date" sword of Damocles having over its head, but it's not a critical application to publish. Everything available to the public right now is accessible through 10.7. Issuing another delay announcement isn't a nice thing to do, but their PR machine can handle it.
It's not worth grinding good people into the ground over something that isn't tarnishing the public image.
