Two Worlds II: PotFF - Preview @ Examiner.com

Examiner.com has a PAX preview of Pirates of the Flying Fortress. It's a fairly short and general overview but it does reiterate the September release date and also claims Reality Pump will be moving on to a new IP after getting this out. A snip:

Pirates of the Flying Fortress continues the story from Two Worlds II, adding roughly 12-16 hours of new quests along with plenty of new items, monsters, and other goodies. Some examples include crossbows, which get their own unique weapon category, a new race called the Olorums, and armor for your horse (of course). Four new multiplayer maps will also be included.

According to Kennedy, Pirates of the Flying Fortress will serve as a vehicle for delivering content that the developers had kicking around in their heads but never made it into Two Worlds II. Expect to see a Night Club for the Undead (complete with dancers) and plenty of side quests with assorted silliness in the same tongue-in-cheek vein as some of those found in Two Worlds II.
