Touch My Katamari is the newest Katamari Damacy game and it is being released specifically for the new Playstation Vita. The video below has a billiards pro demonstrate the concept and changes to the new game.
As you can see you can stretch the Katamari in different shapes that (I'm guessing) allow the Prince into new areas and larger sized items. All Katamari games are pretty repetitive but also quite fun, so this could be a blast. Anyway, enjoy the video, the King of All Cosmos commands it! (And also the Kings cows too, apparently. Moo!)
