Agreed, out of all the rumored IP's, Exorcist: Believer would be the only one affected by the writers strike as its yet to be released. And if it gets pushed back, then we have another Evil Dead Rise situation, which would provide one of the weirder twist of fate situations if Evil Dead Rise ended up being the replacement.
Of course, that's all a big IF right now unless proven otherwise. However if it did happen, I wouldn't mind. EDR was a lot of fun, so for some folks this would actually be a plus to the line up.
