Hello, and thank you for your question @Positivetrucking168,
I'm glad that you are enjoying the small rework for Duisburg city. Many hours went into designing and testing this area before its release to the public. Making good quality map edits can take time. However, we do have plans to start upgrading parts of the vanilla map to either improve the driving experience or give players a reason to visit a different area of the original map. At this time, there isn't much that can be said as far as a possible release, but just know that we are always working very hard to bring players new content.
