OK, so the good news is that Kingdom Under Fire II has been scheduled for a 2013 launch. Unfortunately, the bad news is that so far this release will be limited to Southeast Asia at first. Apparently developer BlueSide wants to see the game in action in that region first before rolling it out elsewhere.
The title is a combination of action-RPG and real-time strategy, promises battlefields with "thousands" of soldiers fighting at once, and will be launching on the PC and PlayStation 3.
