We don't know that. Stiverne didn't get a voluntary. I'm assuming Wilder will get one if Klitschko/Jennings falls through because Povetkin/Perez need to happen first. With the way it's looking, I don't think Povetkin/Perez will happen until the spring. That'll be a long stretch since Wilder is supposedly planning on fighting four times. I think Jennings will be mandated if his fight with Klitschko doesn't happen, though.
Povetkin beats Wilder without a doubt, most likely by a KO. But Wilder won't fight Povetkin, his next fight is against some young hungry lion like Ray Ostin or Solis
Thats what he does. He calls guys out and acts like he wants to fight them but actually have no intention of doing so.
