They always seem to make little improvements over the old versions - gun-metal silver gun-barrels, more colours to the accessories, etc.
The ONE thing that made the 80s toys fun that seems to be missing is the "some assembly required". I don't know for sure, but it doesn't look like they come with sticker sheets for the decals or 20 different parts you have to fit together. They look like they're all pre-assembled and painted... a class above, I guess.
