Ubisoft shows off Tetris Ultimate's battle mode

Not much to say about this really, its the most famous game on the planet and its coming to the Vita with multiplayer modes bolted on when you get bored of trying to beat your personal high score. The various modes were revealed last month, across Vita and 3DS, and the game is due out soon. Oddly the game doesn't appear on Amazon's US site, are they getting digital only?
