Frontlines: Fuel of War now and XBox 360 Exclusive?

[ManusJustusNardus]

Everyone on the internets is saying that Frontlines: Fuel of War was canceled for Playstation 3.  This would make it a default XBox 360 exclusive.  Retailers even took PS3's Frontlines off of their site.  Does anyone have any solid evidence for this and if so why they did it?
