The sneak peek of American Ninja Warrior: USA vs. The World 4, which was aired during SASUKE Ninja Warrior Indonesia 2017: Best Moment on December 30th, 2017.

In my opinion, just like the previous tournament (USA vs. The World 3), this tournament may be aired before American Ninja Warrior 10's season premiere.

P.S.: NBC hasn't released any official statement yet about this tournament (the competitors, the official air date, and the full results). So, NO SPOILER PLEASE!!!
