Ubisoft has officially announced Far Cry 4 and its far enough along that they've revealed it with an official release date - November 18 2014 in North American and November 20 in Europe.
Confirming previous rumours, the game will feature a Himalayan setting:
In Far Cry® 4, players find themselves in Kyrat, a breathtaking, perilous and wild region of the Himalayas struggling under the regime of a despotic self-appointed king. Using a vast array of weapons, vehicles, and animals, players will write their own story across an exotic open-world landscape.
“Following the success of Far Cry 3, we wanted to take the franchise to the next level and create a game that will surprise players and exceed fans’ expectations,” said Dan Hay, Executive Producer. “Given the unique setting, we feel Far Cry® 4 will stand out as a top first-person shooter and we’re eager to reveal more about the game in the coming months.”
There are no screenshots of videos yet, only a packshot. However we won't have to wait too long as a full reveal is expected next month at E3 2014.
