A more likely thing would've been if the maze treatments that Murdy / Aiello made were not to the IP holders' liking and they were forced to make changes (see: Scream, Ash vs. Evil Dead); that would be a more likely cause for chaos. But some IPs straight up not coming because the rights holders felt like it? Unless something drastic happened (probably legal in nature), that just doesn't seem likely.
And besides, wasn't Orlando talking about Alien not too long ago? Now it's Lost Boys? What's it gonna be tomorrow, Insane Klown Posse from Outer Space?
