It would appear that long time users of the rather old but still really nice AI traffic pack Ultimate Traffic 2 will get a replacement soon.
On the closed support forum, only accessible for registered owners of Ultimate Traffic 2, developer Steve Halpern announced that beta testers are needed.
This was posted quite some time ago, so they have probably filled the spots.
The full statement reads:
We have been working on an all new version of Ultimate Traffic. The next edition will be called “Ultimate Traffic Live”.
In short, it takes the best of UT2, along with many new features and a new interface, and provides a totally new product from the ground up.
This will be for the FSX and Prepar3D product line.

We hope to have more news soon. It is still very early, so keep enjoying UT2. As things get closer more info will be posted here.”
