Well, the trailer for the new Sousei no Aquarion OVA, called Sousei no Aquarion: Wings of Betrayal, is finally out and it looks like it'll be good:

At the moment, I don't have much information of what the OVA going to be about, but it seems like we'll have a decent dosage of both past and future events. Hopefully we'll learn more about Fudou, since in the TV series we really didn't learn much about him, just saw him talking crap in riddles. Anyways, go check out the trailer, it looks like there'll be plenty of action. I've heard the OVA will be 2 episodes, around 50 minutes each.
