Koei delays Fatal Inertia… again

What was originally scheduled as a Playstation 3 launch title, has been pushed back one more time. Fatal Inertia, Koei’s futuristic racing game, was originally supposed to come out in February 2007 on the Playstation 3 and get a spring release for the Xbox 360. However, Fatal Inertia is going to be delayed until sometime in 2007. The reason for this is Koei wants to spend more time working on the game to improve its quality. What more could Koei be adding? Cross platform online play?
