An E3 fact sheet released by Ubisoft for the newly announced Splinter Cell: Blacklist, which featured at Microsoft's E3 press conference, confirms that the game will be making the jump from Microsoft's console to PS3 and PC as well.
The fact sheet lists right at the beginning, PlayStation 3 / Xbox 360 / PC, as platforms for the game, and goes on to explain some of the features such as Kill in Motion. The product description is as follows:
The United States has a military presence in two thirds of countries around the world. A group of 12 have had enough and initiate a terror ultimatum called the Blacklist - a deadly countdown of escalating terrorist attacks on U.S. interests. Sam Fisher is the leader of the newly formed 4th Echelon unit: a clandestine unit that answers solely to the President of the United States. Sam and his team must hunt down these terrorists by any means necessary, and stop the Blacklist countdown before it reaches zero.
Expect to play Tom Clancy's Splinter Cell Blacklist in Spring 2013.
