I think that the PSR guy decided right from the start that he would not review any fantasy figures, just historical ones.
As far as I know PSR is run by one person and keeping up with all of the historical sets is a pretty big job; if he's not particularly interested in fantasy sets he might feel the job of reviewing them is best left to someone else.
Sometimes I forget about this and I have spent a fair amount of time searching on PSR for pictures of Amazons or Elves or Skeletons that I was sure I'd seen there before.
