This week, an official German Lego site posted its catalog for the first half of 2015, according to Comics Alliance. In this catalog are several playsets based on The Avengers: Age of Ultron film that is due out in the Summer of 2015. It is possible that these playsets reveal spoilers to the sequel to the successful 2012 film, especially when compared to the trailer to The Avengers: Age of Ultron revealed about a month ago.
Set 76041: Burglary at the Hydra Fortress
The set features Baron Von Strucker, who appeared in Captain America: The Winter Soldier along with the Scarlet Witch and Quicksilver. It should not only be noted that Quicksilver is an included figure with the set, but Strucker seems to be holding Loki's staff. The scene also reveals an interesting element where the Hulk smashes a vehicle, launching Captain America into the air. Is this just the playset box art, or some grand scene from the movie? Whatever the case, it looks like the Avengers will be crashing Hydra's party probably at the beginning of the film, as their fortress is revealed in the trailer.
Set 76032: Avengers Quinjet Chase
This set shows a Quinjet similar to the one in the Age of Ultron trailer, but with Black Widow being dropped onto a motorcycle on the trailer from the jet, not Captain America. The most notable appearance is The Vision, a Marvel comics character and Avenger noted for his red/green appearance and that he is a construct created by Ultron.
Set 76031: Hulkbuster Rescue Mission
This set shows a lot from the trailer, like Ultron Prime and Iron Man in his Hulkbuster Armor. What is odd is Scarlet Witch seems to have this hovering power, which she does not have in the comic book Source material. There is also the Hulk in this weird trap of some kind. The trailer shows Hulk fighting Iron Man as a Hulkbuster, so I would imagine that Bruce Banner is going to lose control and need to be in some super straitjacket of some kind.
Set 76030: Duel with Hydra
There isn't really much related to the trailer in this set. There is Hawkeye in some conflict in a snowy woods on the trailer, and perhaps this is an image from a related scene, but with Thor involved as well.
Set 76029: Iron Man vs. Ultron
The set does not actually have any Ultron in it, but two Ultron soldiers. The trailer did show multiple Ultron minions of some form, so perhaps this is a scene where Iron Man fights a few, with one in an odd flyer. It should be noted that this armor Iron Man wears is one of several within the film.
Set 76038: Raid on Avengers Tower
The set appears to be a Stark/Avengers Tower, similar to a scene on the trailer when Ultron comes crashing in. Note that one of the soldiers of Ultron's army is wielding that Loki staff like von Strucker in Set 76041.
Of course, it may be possible that none of the scenes that these playsets show will be in the second Avengers film at all. In fact, there is a Spider-man playset that looks like something not at all related to any movie. The fact that the Lego Avengers playsets match scenes from the trailer is most suspicious. We'll have to wait until May 1, 2015 to see how accurate they are when The Avengers: Age of Ultron is released to theaters.
