The Japanese release seems to be backed by an EA press release in Japan, but the North American and European releases have yet to be confirmed. Sources believe that we could see the North America release on March 12th, with the European release to arrive on March 15th. Whispers suggest that we will see an official announcement from EA confirming the North American and European releases soon.
The Wii U version is said to support Off-TV Play, which translates into the entire gaming experience able to be played on the Wii U GamePad screen in addition to the regular TV on screen play. Special Wii U features beyond that remain unknown at this time.
Still no news about the expected release date for the PlayStation Vita version, but our sources tell us that it is still in development; and despite rumors, it has not been canceled.
