I actually forgot to cancel my order for Dark Souls. I only really pre-ordered it for the SteelBook, but then it got cancelled. Still, if the previous CE is anything to go by then this is still worth having.
I will just say that the PS3 box art looks much nicer, and blends into where the PS3 banner should be at the top. However, this cannot be said for the X360 version which still retains the usual white / green banner
