In response to a fan request a few days ago, Sapience kindly dropped a couple of Update 7 hints on the forum (here and here). The main details confirmed were:
Update 7 includes the revamp of the Fornost instance in the North Downs.
It will be hitting the Bullroarer beta server “late next week”.
There is no 6.2, update 7 is the next update.
The last point indicates that this update will have to come out in April if Turbine want to keep up with their monthly content schedule that they talked about at the start of the year. Of course, they may not stick to that schedule, but we’ll see.
