I'm 90% convinced that this is going to be a book about FR psionics.
And I ADORE the fact that the XPH is getting a Complete series treatment.
Races of the Dragon could be the one Races book I end up getting, depending on the treatment of it. What I need? Information on role-playing and differentiating kobolds, half-dragons, etc. What I don't need? Yet another dragon-inspired race. I don't like this Races trend being to add another race to your campaign. It's just not gonna work, man. Raptorians will never be as cool as elves, or even avariel! YOU SUCK AT EVOCATIVE RACE DESIGN, MANG!
