Got it on the 28th of Feb !
I took the Limited edition and it is a great (and heavy) package. A couple of friends already joined and we will start playing online soon. (I haven't seen my special wraith yet)
The mythic map pack is also good. 
Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.
