No, it's not. Any exclusive DLC the PS3 version's gonna get is probably only gonna be for HOME. It hasn't been confirmed in any way that the PS3 version will ever get the two episodic packs for the 360. I would like a link to wherever you got your information, because it's more than likely bullshit written by some hopeful fanboy.
arh crap. your right. sorry about that.
just read that the PS3 would eventualy get the DLC so i figured it would also get the packs
