In 2015: 5 sets for Avengers: Age of Ultron and 3 for Ant-Man

Some additional details (via a forumer ofEurobricks who had access to the retail catalog) for LEGO sets based on the Marvel movies Avengers: Age of Ultron and Ant-Man, both expected in 2015:

Avengers: Age of Ultron : 5 boxes would be on the program.

Ant-Man: 3 boxes would be planned around the release of this film announced for July 22, 2015.

The Marvel range will be completed by several boxes (at least two) based on the universe of the animated series Ultimate Spider-Man.

Be warned, Eurobricks is an interesting source of information, but this forum is also frequented by guys in need of digital notoriety who are willing to say anything to get noticed. The above information should be taken with huge tweaks, one of the sources has just admitted to lying ....

Update : The references of the LEGO Marvel Super Heroes sets expected for 2015 are available on a Swiss merchant site which however does not publish the names of these boxes:
