The only thing I still can't figure is: what's coming up that would require the release of the Slim TT!? Is there an existing figure(s) that would utilize that body? Or is it for something new HT plans on putting out? Hmmm..
HT Micheal Jackson is on the slim TT
Preference, maybe just to make some figures with many layers narrower and less bulky, who knows, might look good for Joker with all his layers.
Michael is on the slim, but as far as images I've seen go, he's a modified version with different feet connections than standard TT bodies which the separately sold slim TT will have.
