With the Kickstarter for Warzone, I think it's entirely possible for someone with some cash and desire to get the license to do Chronopia as well. I know there is someone out there who could really do it well too. Maybe this is not the forum to say it in, but I think someone can do it better than Excelsior did. I was not entirely happy with most of the Chronopia miniatures they did. Many of sculpts didn't have the Chronopia look and feel and were a bit amateurish looking. I wasn't into Warzone at the time so I really can't comment on their miniatures for it. I like the rules they put out, but their miniatures were a failure in my opinion.
If I had the money I'd totally invest in the Warzone Kickstarter. In my opinion they are doing an outstanding job of keeping the Warzone/Mutant Chronicles feel, yet giving them a modern and not cartoony look. They are better than anyone has done Warzone, including Target the company who originally did them. I love all the original artwork, but really disliked all the Warzone miniatures.
