Sega today just confirmed that the PlayStation Vita version of Jet Set Radio has been officially delayed. The Vita version was originally due to be released today via the PS Store and that's obviously not happening.
Apparently they need more time to get the game up to par, and an announcement of a new release date will be made soon. Oh well! At least you can score the PSN and XBLA version at the moment.
Read on for Sega's announcement.
