Lost amongst the buzz from Gears of War and Dead or Alive 4 during E3 was the quiet announcement of a Tetris game for the Xbox 360. Japanese publisher Arika announced via its website that it will be bringing the Tetris: The Grand Master arcade series to the system. Tentatively titled T4, the Xbox 360 title will be an original entry in the series and will feature Xbox Live competitive play.
