The Joker content's definitely PS3 exclusive, I know that for a fact.
@Inverted Reality: You could be right, as I haven't played them side-by-side, but I'm pretty sure I saw a bunch more details in the 360 version that weren't in the PS3 one (I've played the PS3 version a lot more). Most reviews say this, too.
Anyone know how substantial the Joker content is? Like how many challenge rooms he gets, for instance?
