Miller shooting two Mad Max films?

Twitch today stated that George Miller is shooting two Mad Max films back-to-back for a quick release. The first film, we do know about as Mad Max: Fury Road and stars Tom Hardy, Charlize Theron, Nicholas Hoult, Zoe Kravitz and Adelaide Clemens. The proposed second will be called Mad Max: Furiosa. Until the studio or Miller publicly announces this, consider this a rumor, although Twitch claims it’s from a close source, naturally.
