While 6 houses would be disappointing, I'd be able to live with it as long as the rest of the houses were strong and there was plenty of extra entertainment.
I'm assuming Minion Mayhem will be open, which gives the event an extra ride. And maybe they'll do something like open ET if they're worried about capacity? I dunno. I'm also going to assume that we're getting a special version of Cinespec for a showing or two, which would help as well. And while I know it has a bad rap in the fan community, maybe showings of Beetlejuice or something?
I figure they're going to have to do some things to shuffle people around here.
