For myself I think it's the All new Xmen which has my attention at the moment, simply because it could lead to some of the teenage X-men being given a complete freak out moment. I know Gman has said it a few times on the Podcast but how is Jean going to react knowing in the future she's dead and has a school named after her, also you've got Scott finding out that he in prison for the events of Avengers Vs X-men and the most important question is this. Will this effect the younger versions of themselves to a point where they are scared of the future.
I'll probably pick up a version of the Avengers and deadpool down the line.
Personally I would rather see the Avengers take on a smaller threat (like a returning Hydra and Red Skull or a team of super villains), however if Joss and co want to bring in Thanos in the second film then there has to be something worth doing with him and then have something even bigger for the 3rd one (I thought I read on here that one of the ideas was going to be the Civil War story arc)
