Save the date, fight fans. It appears the UFC will make a special announcement on Nov. 17.

The organization today sent reporters a save-the-date email, though few other details were given about the nature of the news.

According to the email, which included the caption “The Time is Now,” the announcement takes place Nov. 17 “for a can’t-miss event in Las Vegas.”

The UFC, of course, is headquartered in Las Vegas.

The upcoming event comes two days after the UFC makes its debut in Mexico on Nov. 15. Mark Hunt and Fabricio Werdum fight in the headliner of the pay-per-view event, UFC 180, at Mexico City Arena. However, it’s not clear if the announcement has anything to do with the UFC 180.

So what’s your guess for the announcement? Georges St-Pierre or Brock Lesnar’s return? The signing of Gina Carano? A new UFC Fight Pass offering? A potential blue-chip sponsor? A long-rumored UFC uniform? “The Ultimate Fighter” coaches announcement? An event or venue announcement? Something else?

Let the speculation begin, and give us your prediction below.
