He did reply to some people who commented saying he probably meant the Origins story and he said that wasn't the case and this is a new development, but he deleted those tweets for whatever reason, but he hasn't debunked these many reports of a spinoff that he started which he probably would do if he was just using it in a way to say don't celebrate yet
