Jet Set Radio was intended to get a Vita release within a month of the PS3 and Xbox 360 release. It doesn't look like that's going to happen.

Sega has confirmed that the Vita version of the game has been delayed "due to necessary development optimizations." Apparently you can't just slap a PS3 game on a Vita memory card and expect it to work. Who knew?

No new date has been announced, but it doesn't seem like the Vita version of Jet Set Radio will be hitting virtual store shelves any time soon.
