I'll probably pick up the Complete Divine, the Psionics book, the Planar guide, and Unearthed Arcana; I don't know about the races book, and I can almost guarantee I won't pick up Eberron.
I've gotten to the point where I love WotC products for the variety or rules, feats, and other crunchy bits; they are great for establishing a "norm" in my games. However, I tend to stay away from purchasing campaign settings, whether they are WotC or not. There is certainly some quality material out there, but I don't feel like (A) uprooting my game to a new world or (B) modifying everything in a setting sourcebook to fit my games.
As for the races book (and probable entire line of such books), I will wait and see. Chances are, I will like them and add them to my collection, but I thought Savage Species would have been a useful addition instead of being a min/maxer wet dream.
