I'm a big fan of the Warhammer 40k universe and enjoy both Dark Heresy and Rogue Trader. Admittedly, I find Deathwatch a little odd, limiting in over all scope compared to the previous games, but I suppose popular among those who want to add RPG elements to squad based table top games.

In any case, in each system I've noticed a relative lack of Eldar. Sure we have Dark Eldar popping in here or there, but little on the core Craftworld Eldar. Why is this? It seems to me that Craftworld Eldar could be the subject of just as many stories and adventures as any citizen or soldier of the Imperium... Are there any plans to include more in splat books?
