Koei revealed the release date today for its futuristic racer Fatal Inertia for the Xbox 360, with a PLAYSTATION 3 ship date conspicuously absent. While the 360 SKU will ship this September 11, according to the Koei reps we contacted for clarification, the PS3 version has been "delayed indefinitely."

Citing a delay "due to the completion of the Unreal Engine 3 for the PlayStation 3" the Koei Canada-developed title appears to be an unplanned Xbox 360 timed exclusive, pending further developments. The game was at one point a PS3 exclusive, but experienced development difficulties and missed its intended November 2006 release date.

After hints at that PS3 exclusivity dissolving from Koei management at Tokyo Game Show and failing to launch alongside the PS3, an Xbox 360 version was revealed earlier this year.

Now we wait for Koei to quietly kill the PS3 version altogether, further developer difficulties and the sun to set and rise again over the horizon.
