Funcom's Joel Bylos has published the latest Game Director's Letter on The Secret World's site. In it, he reveals that Issue 7 will be making its debut in a few weeks and drops some interesting hints about Issue 8 and an attack on Agartha itself.
Firstly, the content: Issue #8 begins when the players are instructed to complete training with the Council of Venice in order to certify them as prepared to face the chaos in Tokyo. This is achieved by completing Scenarios.
Scenarios are virtual worlds created for the sole purpose of training the player to deal with situations that arise daily in The Secret World. Because this feature can be expanded in many ways, we will add additional Scenarios at a later date. Scenarios will be available for both group and solo play, and they will have different levels of difficulty.
These scenarios are designed to be repeatable through the use of certain highly random elements. This means that a scenario will play out differently every time and that players will need to adapt to circumstances on the fly.
