On the topic of video game IPs which could show up, I do agree that The Last of Us pt. II and Silent Hill are in that boat, each with their own reasons.
The Last of Us pt. II - Unless I'm wrong, I think the first house went over pretty well between HHN, Sony and Naughty Dog (especially over in Hollywood), and with the highly anticipated next season of the series coming out, it would line up nicely for another house at the event.
Silent Hill - The franchise has been climbing back into the spotlight thanks to the remake of the 2nd game, and the movie Return to Silent Hill is in production/maybe releasing next year. Also, Silent Hill has something unique going for it, as Murdy from Hollywood has expressed interest in returning to the IP. And Aiello over here has stated he would love another shot at Silent Hill as he felt they didn't quite get it right the first time. When the directors for both coasts have an interest in returning to an IP, that's gotta' be to its benefit as a creative members interest/passion in an IP/theme can help make it get picked.
