An epilogue is a final chapter at the end of a story that often serves to reveal the fates of the characters. Some epilogues may feature scenes only tangentially related to the subject of the story. They can be used to hint at a sequel or wrap up all the loose ends. They can occur at a significant period of time after the main plot has ended. In some cases, the epilogue has been used to allow the main character a chance to 'speak freely'. An epilogue can continue in the same narrative style and perspective as the preceding story, although the form of an epilogue can occasionally be drastically different from the overall story. When the author steps in and speaks directly to the reader, that is more properly considered an afterword. It can also be used as a sequel.
And anyways, my whole point was that RavenTwoFive is mistaken. What I have been saying has nothing to do with season three. Perhaps if I had a deeper understanding of how animes get the green light for renewal and the success rate of shows getting a third season and other underlying issues in the business aspect, I could possibly shed some light on the subject. My lack of knowledge doesn't really lend a hand to help on the subject.
If there is no news of a season three by the end of this year, It seems unlikely that they would continue the anime, but thats just my speculation, i have seen a few animes that got their first season years ago then got a new season like 3-4 years later, but this does seem a little different. We also need to take the japan disaster into account.
