There are a lot of creative and talented people on this board. I wouldn't be surprised at the sheer amount of awesome stuff (photos, custom dioramas, custom re-sculpts, re-paints, etc) that will be generated from using the DX TDK figures as a base for creative expression. Personally, there was a really neat alley way custom dio made by someone (forgot the name) that I'd like to see with the DX figures taking place of the previous ones.
It's going to be exciting, Although the 6-7 month gap between the DX Joker and DX Batman is a bit of a dampener.
