Not all city pairs are served but it's the best approximation for a crystal ball that I know of.
It is NOT a crystal ball. It is a historical trending tool. If one assumes that fares should match what they historically were then it is a pretty good resource. I think that is a pretty bad assumption right now.
Oh, and FareCast shows the bottom at ~$200 and trending upwards right now.
