Just read an article saying it would run the same on all three platforms yet in the same article it was desingned for the PC & PS3, heres a snippet...
"Our goal has always been to create a game that works equally on all platforms," he said. "So the engine is designed to run smooth on the PS3 as well as on the PC."
Back avoided making direct reference to the Xbox for obvious reasons, but did continue: "I think the consumer will not see any big differences between the versions."
Notice the "big", meaning some differences not indentical on all,
So this is confusing, it seems that DICE are quietly stating that in terms of their games quality it goes PC, PS3, then XBOX.
