People need to remember that Sinister and its sequel are not Universal properties (just as Paranormal Activity and many of their smaller, earlier films aren't).
More importantly, though, Sinister is not considered a franchise in the eyes of Blumhouse; Jason has said as much in interviews. It was intended to be another long-form series (ala Insidious), but those plans cratered with the financial failure of Sinister II.
I don't have intel on this year, at least in this capacity. But I'd be surprised if they went for a full-blown Sinister maze when that IP isn't a priority for basically anyone, regardless of how well-received it was by guests. (There wasn't a whole lot of internal enthusiasm at Blumhouse itself, for what it's worth.)
