News: According to the ESRB it is.
For a long time it has been safe to say that very few games remain console exclusive for long. It hasn't changed yet.
Seems Koei's futuristic-racer Fatal Inertia can't make up it's mind on what console it wants to be on. First it was PS3, then it was Xbox 360, now it is both.
A recent search on the ESRB shows the game is heading to PS3 listed as Fatal Inertia EX. How many PS3 owners care? Probably not many at all. Perhaps they already forgot about the game thanks to WipEout?
Stay tuned for more info on Fatal Inertia.
