Interesting results.
Personally I would like to see some new settings emerge for 4e. I enjoyed playing in multiple campaign settings throughout the 3e years, but I never had as much enjoyment until I discovered Midnight by Fantasy Flight Games- that was my gaming heaven for 3e. And as much as I love the Midnight setting, I don't see it working well with the 4e system. That being said, I would love to see a campaign setting for 4e that would inspire me as much as Midnight did for 3e.
