Just for further clarification, the expansion pack isn't being done by A2A, but is being done with the permission of A2A - thus its not some 'official' expansion pack being managed by the product company. It doesn't do anything to the exisiting AF Corsair aircraft that you have - it makes a completeley separate folder of aircraft (textures, flight dynamics, code) that utilizes the sounds and models from the original product, and so is otherwise stand-alone. No word yet on an exact release date, but it sounds like it could be soon.
