Good point. I know that people have counted the amount of Reapers, but there is no way that there's only 300 of them. Think about it. There is no way that they alone could have destroyed the Prothean Empire.

But that really makes me wonder though, how many years into the future does ME3 take place? Story wise, there is no reason why we should believe that ME3 doesn't take place in 2185. However, like I mentioned earlier, there is no way that the entire Reaper Fleet could move that fast. And they were at least a couple thousand light years outside of the Milky Way.
