So a "friend" of mine has access to some Pokemon USUM information.

But all they were willing to share was a blurred out image of the new Lycanroc form. They think that will be harder to trace back.

The Lycanroc Dusk form was revealed recently due to it appearing in the anime. But this form will be saved for a later reveal. Sort of like the Mewtwo and Charizard megas. Introducing one form much earlier.

It may not even be revealed until the games release.
