I don't care if they do or not, because I have all of the TDK-specific pieces from a parted out DX02. I imagine most DX02 owners wouldn't mind either, unless they'd be annoyed that the DX02 will lose everything that made it unique in the first place if it is all included again with this version.
It would be like including the Police Uniform and Grenade rig with the Joker 2.0...it would completely eliminate any reason to have the DX01 (except for wanting to be "first").
That said, besides the EMP gun and "Bat-iPad" I haven't noticed any other new gadgets in the TDKR promo shots and trailers. There's going to be plenty of room on the TDKR DX box for a Sonar-head, Sticky-Bomb gun, and Cape Backpack...and Wayne head (plus the standard grapple, batarangs, and bombs) if Hot Toys decides to give us the ultimate TDK(R) DX Batman.
