Coming Soon: Map Pack 4.0 - Will be implemented soon after Delta 313 arrives. Likely sometime in August... More to come!
Map Pack 4's goal is to coexist better and compliment the normal game's maps rather than to reinvent the wheel and create a totally different experience which is what's currently going on.
Some updates will include using the vanilla game's geography and POI data rather than to maintain a separate database of this common data. ALL of the common buttons will exist from the vanilla game install in Map Pack 4.0. More updates and details will be revealed later.
