I'm not sure there needs to be another line. At first I thought it would be cool to play Eldar since back in the day when I used to play the TT game it was Eldar that I ran with. However I don't see them having much in the way of RPG material. I'm going to borrow from WW on this but I think what would really be awesome is if next year kicked off the Year of the Xeno. In which they released several books that detialed all the games Xeno races and rules for adapting them to the various lines. You could put in notes for making them PC's and what not.
Please, Ezekiel. My jobs not to decide who lives or dies. My business is with the soul. And I have never damned a soul that didn't throughly deserve it. Mother Nature is a completely different story.
