Brian Provinciano has posted up a detailed breakdown of Retro City Rampage's cross-platform availability, clarifying the game's current status for overseas release and revealing that versions for Xbox Live Arcade and WiiWare are now in certification.

Provinciano notes that the WiiWare version of his open-world, multi-genre parody will "hopefully" premiere this month, while the XBLA edition's release date is more difficult to predict.

In addition, a European PSN release will likely arrive "before Christmas," and will benefit from a month's worth of additional development time and polish. Provinciano also claims that there are no plans for a sequel for the time being.
