Considering that the first iteration of the map from the A-10C beta days was thrown out and they started again from scratch, and that the map was not only being built but was used to help develop the tools, technology and framework for future EDGE maps to come, and the fact that a large chunk of the user base is going to get the map for free because they pre-ordered the Warthog beta, the price is well justified. They have to make money off it somehow...
