Rumor was it was pulling from TCM 3D and going for a different aesthetic?
Anyway, here's my speculation on announcements because I'm doing massive reworks of my TP HHN stuff:
June 17 - Popular IP to anchor ticket/pass/package sales
June 24/late June - Jack/30th/Icon house/theme reveal
Early July (July 8th, lets say) - Texas Chainsaw Massicre
Mid-July - re-announce Bride/Tooth/Puppet (fan favorites from last year's daytime event, coming to HHN for the first time, etc)
End July - Scarezone/shows
Early August - Shrek location announcement (H3/Creep/OG)
Mid August - Remaining original houses
End August - food/bev/merch previews
