Hej planespotter
Team Fusion is working on it as you speak. They have come along more problems than expected, but they stated that they now want to go deeper into the AI, so it´s probably better if they take their time to do it properly... Afaik, they want to get the Radio-Comms working for TF 5.0 (timline is half a year).
As for 4.01, it shouldn´t be such a long time to wait, maybe a couple more weeks...
The history of Cliffs of Dover is one of waiting, so a couple more weeks won´t matter...
