Well the 80’s definitely seem to play a large role in the speculated house lineup, and this line from the blogpost of Stranger Things seems to indicate a general theme of the past in the mazes:
“This year, the past will haunt you with brand-new mazes based on iconic horror films, terrifying hit TV-shows and haunting original stories.”
Hopefully they carry it over into the zones too. Really curious about the originals this year though
