As to what Teugene said, I don't think the Reaper fleets seen are different fleets. I thought I saw Harbinger at the head of both fleets. My guess is just that it is an oversight which assumes people have finished the game. But good theory. I actually thought in Mass Effect 3, the Reapers would enter through the Dholen system. But they're on the other side of the galaxy... So perhaps a second Reaper fleet is lying in wait to surprise the galaxy, or there's a plan D.
