Well, maybe they will go one more year without an update since iOS 9 will run on it, but I would think not well. I don't expect a mention in any keynote, they would probably just do a silent website update. I would be surprised if they didn't updated at least one more time, but if they don't update soon they will have no choice but to drop it. They won't sell phones with iOS 9 and iPod touches with iOS 8.
