I wouldn't say it is certain, but it would be shockingly incompetent of AKG that a statement like this was made on their official facebook page if there was not a replacement in the works.
My organisation has a facebook page - very few people have access to it, everything that is posted on it is debated to death and signed off pretty high up the chain of demand. I don't see why any large organisation would see facebook any differently.
Facebook is a massive audience, I find the idea that any serious corporation of AKG's standing would consider it the way some posters on this thread seem to be suggesting they would - casually, flippantly and like a gossip site - utterly naive.
If that is the case (and I very much doubt it is) AKG need to seriously be looking at cleaning house and starting from scratch with their marketing department.
