From the new issue of EntertInment Weekly, which I guess isn't out yet but someone on the CBR boards has access to it.
Uncanny Avengers: (oct 2012) written by Remender. It is going to be the new flagship marvel title and will have among others Cap, Thor, Wolvy, Rogue and Havok in it and both sides will still have some AVX tension.
Avengers (dec 2012): Bi weekly with more then 18 avengers on the team. Written by Hickman with one shot stories and longer galaxy spanning multi-issue arcs
X-men: (nov 2012) hold on to your hats...... Bendis!!! about the original five x-men time-travel two the present in a pleasantville style story and who are not going to like what they see once they are in the present and will find it unacceptable. Bendis says the time travel aspect of the story is not as important as the character based drama.
This is just a promotional image, not a new team.
