This is an interesting question...

Every other TW game has had a Prima or Bradygames guide release with it. The high point being the MTW Bradygames guide with the actual calculations for combat from the game.

I do support a user created guide, but considering E:TW is topping PC sales charts all over the place it seems like a big loss of potential revenue not to have pumped out some from of hardcopy guide.

It could be that they where working on the game all the way up to the wire (and they are still working of course) and simply didn;t have the time for the guide...

Still, it is a little odd...
