Crytek have been teasing about their upcoming reveal in April. It seems though that the reveal has been leaked ahead of time, by Origin of all places. The advertisement went up showing the box art as well as a chance to add the game to your cart.
I think this may lead EA to rush the official announcement of this really exciting sequel. The first game was set in the North Korean jungle, while the second game was set in New York. The box art however reveals broken-down buildings meaning the game may be once again set in New York although that is just speculation. Expect a full reveal from EA soon enough.
