Assassin's Creed 3 - Officially announced for Wii U

Ubisoft Press Release:

Paris, France — March 5, 2012 — Assassin’s Creed^® III will hit store shelves on October 31, 2012, encouraging gamers to experience the American Revolutionary War not written about in history books.  The largest project in Ubisoft’s history also introduces a new hero for the ages.

 With a development cycle of over three years and twice the production capacity of any previous Ubisoft game, Assassin’s Creed III is set to release on the Xbox 360^® video game and entertainment system from Microsoft, PlayStation^®3 computer entertainment system, Windows PC and is also in development for Wii U™ from Nintendo. Assassin’s Creed III is developed by Ubisoft Montreal in collaboration with six other Ubisoft studios.

 Set against the backdrop of the American Revolution in the late 18th century, Assassin’s Creed III introduces a new hero, Ratohnhaké:ton, of Native American and English heritage. Adopting the name Connor, he becomes the new voice for justice in the ancient war between the Assassins and Templars. Players become an Assassin in the war for liberty against ruthless tyranny in the most stylized and fluid combat experiences in the franchise to date. Assassin’s Creed III spans the Revolutionary War, taking gamers from the vibrant, untamed frontier to bustling colonial towns and the intense, chaotic battlefields where George Washington’s Continental Army clashed with the imposing British Army.

 Assassin’s Creed III is powered by Ubisoft-AnvilNext, a revolutionary new game engine that delivers breakthroughs in visual quality, character models and artificial intelligence. Assassin’s Creed III will feature a ground-breaking level of stunning graphics that bring Colonial America to life.

 “Assassin’s Creed III features the franchise’s most expansive setting so far, along with an exciting new hero and exponentially more gameplay,” said Yves Guillemot, chief executive officer at Ubisoft. “Whether you’re a longtime fan of Assassin’s Creed or if you’re new to the franchise, you’re going to be blown away by the scale and marvel of Assassin’s Creed III.”

It has been said  elsewhere  that some of the trailer is using the in-game engine to render it. Those are some mighty impressive visuals for the character models, and it wouldn't surprise me if they were showing the PC or Wii U version of the game.
