Off the top of my head, the big names that haven't been added back yet are Englund, Linda Blair, the Karate Kid/Cobra Kai reunion, and Big E/Xavier Woods.
Englund is out for sure. They replied to a post saying that Linda Blair wasn't currently booked for November but that could still change, and no word on The New Day, but I'm going to guess with WWE's touring schedule it is tough to just shift those dates around. No clue on the Karate Kid guys.
Overall, I'm happy with the guest lists. And like I said before, I'm *really* happy they haven't forgotten the comic part of comic con. They've got a really good writer and artist lineup on top of celebrity guests.
