* NOTE: When I say (debunked) it means that
@Legacy responded in a fashion that would make it seem like this is NOT the answer. Also, he has pretty much stated anything stemming from Veronica Mars is incorrect so I did not list those here.
** SECOND NOTE: The fact that Legacy intimated that this could be the first announcement, I STRONGLY believe it would be an IP instead of an original (since IPs are almost always the first house announcement). So I'm going to strikethrough "original" guesses on that premise.
*** THIRD EDIT: Stuck out Hellraiser and Candyman because
@Legacy debunked those too.
