A new game based on James Cameron's Avatar is in the works at Ubisoft, but don't expect to get to play this game anytime soon. The publisher confirmed to IGN that the game won't be released until after the company's Fiscal Year 2021. What this means is the game will not be released until April 1, 2020 at the very soonest. The long-awaited Avatar movie sequel, Avatar 2, is coming to theatres in December 2020, which Ubisoft referenced in its statement.

"Avatar is one of the biggest and most powerful entertainment brands ... we have great plans for the new one, with a very strong studio and engine. The movie will be released end of 2020, so our game won't be released before FY21," the representative said.
