Only one report so far (not double counting):
"Apple laid off 40 of my old Final Cut team yesterday, lots of good people, despite high profits."
By the way, Pete Warden, who once released free AE filters, was featured on ReadWriteWeb a few days ago in The Man Who Looked Into Facebook's Soul.
Update: The post isn't wrong -- it just reported a Twitter item. And while it doesn't mean that Final Cut is doomed, it is interesting that Pro App teams in LA and Austin seems to have been cut confidently before NAB. Then again Adobe laid off about 600 workers in 2008 and another 680 in 2009 (about 9% of its workforce each time).
By the way Pete Warden's filters haven't worked in recent versions of AE (they were released before he worked at Apple), but they are open source so someone can build on them.
