Marvel studio head Kevin Feige revealed two new Marvel movie titles in Entertainment Weekly’s Avengers issue (see “’EW’ Covers ‘Avengers’”): Guardians of the Galaxy and Inhumans.  Feige said of Guardians, “There’s an opportunity to do a big space epic, which Thor sort of hints at, in the cosmic side of the universe.”  Feige also mentioned Inhumans and the long-gestating Ant-Man as possibilities.
The surprising titles on Feige’s list may explain the three “mystery” slots that Disney has reserved in 2014 for Marvel films (see “Disney Reserves Slots for Marvel Mystery Movies”).
