"Retro City Rampage is finally launching October 9th on PS3 and PS Vita in North America and on PC / Steam / GOG worldwide. The European PS3 and PS Vita releases will follow later this month, WiiWare following shortly after that. The XBLA version is 99.9% ready to get out the door, but still waiting for a release slot.
I made the decision to release the game on each platform as soon as it's through certification rather than wait any longer in an attempt to achieve an absolutely simultaneous launch.
For a chance to play Retro City Rampage even sooner, head over to your nearest GameStop. The PS Vita version will be playable at GameStops across the United States starting this month, hopefully by the time you're reading this!"
