Sega announced yesterday that their re-release of Dreamcast cult classic Jet Set Radio will coming to PS Vita, in addition to PC, XBLA and PSN. Unlike it's non-handheld cousins, however, the Vita version will have touch-screen controls and camera integration, so you can get the full rebel-graffiti artist experience.
I'm honestly not sure what the camera is going to be used for, but I'm sure that like everything else in JSR it'll all make sense once we get our hands on it. The Vita version will make its first public appearance at E3 in a couple of weeks.
Jet Set Radio will make its mind-blowing return sometime this summer.
