True. There's not yet a list of confirmed races for the 4E Eberron campaign setting so it'S possible some of them might be in PHB2.Irda Ranger said:WotC might think there's was enough "Core appeal" for those races to do that.
I'd hope though that the new races for PHB2 will be chosen to be a good fit for the probable power sources in the book, i.e. psionic, primal, and ? (shadow?)
