It appears the Aerosoft A320/21 Professional will be delayed a few days. The package was scheduled for release for September 6th, however, in a post in the Aerosoft forums, project manager Mathijs Kok wrote: “I decided to push the release to next Monday. We have a few files inbound I really want to include and we do need the time to check that the adjustments to the shop software are fully okay.”
So from what Mathijs is saying it looks like the new release date is going to be September 10th. In addition, the official preview video for the package was released and can be viewed here, along with some new screenshots.
