User blog comment:Kaloneous/Mass Effect 3 Ending DLC Denied and PAX/@comment-4319257-20120317170324

Just a speculation in support of future "true ending" DLC. Both ME 1-2 had a definite Reaper in the game, destroying which was the main objective of said games. In ME1 you could converse with Sovereign, and then you had destroy him in the end, in direct confrontation. In ME2 Harbinger was behind all stuff, but the immediate threat was the Human-Reaper, which again, you had to destroy in the end in direct confrontation. Though the main villain of ME3 is supposed to be Harbinger, as a leader of all Reaper forces, he doesn't really show up. He's just briefly mentioned, as the final battle is in progress. Even if he's presumed to be destroyed/contained, you don't deal with him directly. Kinda breaks the consistency. So... Using this logic, the true ending must happen in the future, and Harbinger must be involved directly. Hope so.
