Considering it would be better to wait for at least teasers to be released before making the announcements, and considering if Jigsaw turns out to be the our SDCC maze announcement, along with AVED being our next one, those other two will be most likely either near the end of the month or beginning of August. Though it really depends on what exactly we're getting as the replacement. If it's Alien, it may get announced before several others, but if it's Leatherface, then, like Insidious 4, they may wait for a trailer to be released to go along with the announcement.
