I do however know that it is to be published by Marvel in October. That it is $3.99. That it appears to be a thematic take on A Vs X and, thus might indicate a joining of Avengers and X-Men after their bitter conflict. And that it is by Jeph Loeb and Dale Keown.
UPDATE: Yes, this piece may have originally mentioned Warren Ellis. No he's not on it. Looks like it may have been an echo from an earlier proposed version of the project… Warren tells me "I don't think I actually know what that is. Nothing to do with me, regardless."
