'Gravity Falls' Finale 'Weirdmageddon 3' News Update: "Gravity Falls" creator Alex Hirsch has been tapped by Fox to develop a new animated series, according to Variety.

"The rumors are true!" Hirsch wrote to Twitter. "I'm cooking up some new strange projects for some new strange places. 2016 is gonna be a crazy year buddies."

Details of the new show are being kept under wraps.

"I'm cooking up some brand-new weirdness," Hirsch promised Variety.

"Gravity Falls" is ending with a final hour-long episode, "Weirdmageddon 3: Take Back The Falls" on February 15.

"The first thing to know is that the show isn't being cancelled- it's being finished. This is 100% my choice, and its something I decided on a very long time ago. I always designed Gravity Falls to be a finite series about one epic summer- a series with a beginning, middle, and end," Hirsch wrote via a Tumblr post.

"Will every single conceivable question ever thought of about Gravity Falls be answered in the end? Of course not. But that just leaves some material for any potential Gravity Falls projects in the future (including the canon Journal #3 that goes on sale in 2016),"  Hirsch explained on his Tumblr page.

Wired reported on a theory posted on Reddit "that fans' obsessive deconstruction gave them too much insight about the show's ultimate twist, so Hirsch himself decided to cut short what was originally meant to be a longer series." 

Gravity Falls was for the most watched animated series of Disney XD.

"Weirdmageddon 3" may feature a showdown between "Gravity Falls" antagonists Bill Cipher and Time Baby.

Hirsch hinted on his Twitter months ago that "At least one character will not survive the season. Buckle up."

 "Gravity Falls" has aired 39 episodes since its release in 2012.
