Forum-member Breten has done translations of the stat cards for the Westerners, Saracens, Lost and Demons.
I'm told that an actual physical English-language rulebook is a while away yet - after the Spanish version at least. Like Darth-Swen says, PDFs of the cards and rulebook (the bits that aren't done already, like scenarios and terrain rules) should be along "soon". Your guess is as good as mine as to when "soon" will be.
