All the Phase 2 movies (IM3, Thor 2, Capt 2, Guardians) all happen at the same time, this has been confirmed by Marvel. That means that the after credits scene will not lead to those movies, as by the time that scene is happening in the time line, all of the events in the other movies will have already happened. They will all lead up Avengers 2, and/or maybe hint at Ant-Man's existence (Post Phase 2). But most likely just Avengers 2.
