The price will be similar to current GSX, but there will be a lot more value in it, because many features which were only available with GSX L2, like Passengers, replacement Jetways and the Fuel Hydrant, will all be part of the Base product.
Also, the base product will also replace all default Ground Vehicles, on a Global basis, without being constrained by the limited "Regions" system, and they will serve AI airplanes as well, something GSX never did before.
