Yes, there's a Super Monkey Ball game on PlayStation Vita, because the Vita is a device capable of playing video games. Sega has officially begun promoting the game in Japan, announcing a June 14 release date in that region, and a Japanese title: Super Monkey Ball Tokumori Asobita! (It's Super Monkey Ball: Banana Splitz over here).
The Vita game features a level editor that allows players to generate new Monkey Ball levels from photos. There's also a weird two-player co-op mode that tethers two Monkey Balls together with a line. Other than that, it's the Monkey Ball you know and loved until you got so frustrated you swore you'd never play again.
