Hopefully there isn't. The reason why I say that is becuase with Dread Lords, the manual was horrifically out of date by the time the game was released. I would hope that they wait a bit longer to do the manual, that way it is more accurate.
Most of the information you can find on the forums, you just need to poke around some. Stardock has the most responsive devlopment team I have ever seen, so if you can't find it on yur own, you can always ask, and will probably get an answer fairly quickly.
