I'm confused: you consider the BB and TDK Batman as 2 different figures because the differences with the suits, yet you DON'T consider the v.1 Joker and Bank Robber Joker 2 different figures!? Even if the head sculpt would've been 100% accurate with the v.1 Joker HT still would've released the BR version because it's significantly different than the v.1 Joker both in costume and accessories. I actually saw people trying to mimic that BR look with their v.1 Joker's before HT announced the Bank Robber version. I saw people asking for HT to release the BR Mask, Handgun w/extended clip and Machine gun. Not only did HT do that, they added in a nice duffle bag with smoke/regular grenades and a 2nd headsculpt specifically for the mask. imo there's enough there to warrent a new figure and people who got the v.1 figure shouldn't feel ripped off because they're lucky: they'll get a new film accurate head to pop onto their v.1 Jokers and they'll get an additional figure representing Joker from the Bank Robbery scene. I wish I had the v.1 Joker.
I consider the two Batman figures two different figures because... well, only the inner body is the same. And I do consider the Jokers two different figures too. The thing is: If you buy any of the Batman figures you get a figure as good as it can get: Begins or TDK costume. But with the Joker, the only way to have a perfect purple suit Joker is to cash two figures. I guess there's a difference that is pretty obvious, dont you agree?
