So I have an idea for the rumored seventh set. Supposedly some Lego Store workers have commented it includes a big-fig. I wonder: what if the set were Thanos’ Sanctuary II?
It could be just large enough to seat a big fig in the interior with the long wings built onto the sides of the hull, and it wouldn’t have to be the most expensive thing. Given he isn’t directly in combat, this could include him without the armor, in addition to an Infinity Gauntlet without any of the stones. (I mention this possible inclusion because of the extras included in the other six sets).
It would also serve as an opportunity to include eye-patch Thor and Loki depending on the setting, as well as characters we didn’t get in the ragnarok wave such as Heimdall and Korg (like how we got Shuri after the Black Panther wave).
