I think you guys are forgetting how bare bones most of these DX releases have been. There haven't been too many alternate heads or clothes. In fact with the DX line you get less bang for your buck now.
If this Joker release is like the Nicholson Joker and is just an update of the regular purple outfit then I'd be happy with the following.
- Smiling head (with a lighter yellow/green hair)
- better tailored, more accurate outfit
- brighter purple coat
- orange lining
- blue sports coat
- knife shoe
- RPG
- pipe/bar
- snub pistol
- Remington sawed off shot gun
- detonators
- regular hands (for the interrogation stuff)
- gloved hands
That's a pretty definitive release, I'd be happy. It would covering accessories and weapons that haven't been done, a head sculpt that Hot Toys haven't given us all while being along the lines of their Nicholson Joker, '89 Batman, Jack Sparrow and T-800.
