During an Italian languaged interview of Asmodee Italia, information about set 6 was unofficially announced. It is expected to land in October 2021 and will feature a significant return of a house (rumored to be Mars). A new house will also be introduced and will be heavily influence by East Asian aesthetics and customaries, presumably the new house will be The Inspired. Ofcourse the return of a house, and the introduction of a new house inevitably means the rotation of one or two other houses.
Popular opinion among the community is that the new set will be announced during Gen Con in September.
