X-Men: Days of Future Past
Captain America: Winter Soldier
Both of these look absolutely amazing! To be honest, I'm mostly excited for X-Men, seeing as that was the first comic book fandom I got into then followed by Batman. Captain America looks like it's going to take an interesting look into S.H.I.E.L.D and see what it's really becoming and that is going to be great to watch, maybe becoming more political than just superheros in action.
