Basically the actual batman figure itself is essentially the same a the dx12 but with new face plates, smaller versions of the qs001. It also seems to have a slightly new belt as its in segments or links like the dx12 but is a clean belt with all the little canisters and stuff that can be added, again I think this is like the qs001.
Other than that it's the obvious stuff from the pics, such as not including the EMP gun or steps base. Also, I've mentioned this before so I may sound like a broken record, but one thing they've included that I love is the grapple gun holster. I loved that look in the dark knight.
