I apologize for the pics.. I couldn't find any other to make my point. Obviously that TDK Batman in the photos was HEAVILY modified.. you can even see the dull areas where it was dremmled. Unfortunately, it's distracted everyone and instead of focusing on what I was getting at, everyone focused on the pics.
My point still stands: no mention of ANY modification is mentioned in the official specs from HT that's still on their site. So imo it is possible that HT could be using a modified TT, even if it's just slimmer shoulders, and NOT mention it like they did with the TDK Batman. Now.. HT did eventually mention it, but it was mention outside of the official specs:
