EA has revealed that the Dantes Inferno demo scheduled for this month will land on PS3 two-weeks ahead of the Xbox 360 demo.
Called Gates of Hell, its the first level of the game and set for release on December 10. XBL gets it Christmas Eve or December 24 for the oblivious among us.
Full thing is out in February.
