Based on what they've done with the bank robber joker, what i'd expect to see in a TDK suit v2:
Sonar lenses Head (with lightup eyes, or just painted, lights would be cooler)
Honk Kong scene BackPack
Removable cape (to swap pack)
Sticky bomb gun
Bruce Wayne Head
That's why I held out and didn't get the v1 TDK Batman.
The only reason to do a third Batman would be the HK version. Plus, with HT, it's the home costume. It will be done.
