Sometimes, I think that astronomy and astrology are a divorced couple who are fighting over their children - the planets. And, of course, Pluto is the focus of most of the fighting, since he is the problem child, the runt of the litter, the black sheep of the family.
That said, I don't think Pluto being demoted to a dwarf planet by astronomers will drastically alter astrology. Astrology has evolved over time and this is just another step in its evolution. It'll be interesting to see how things change and what new ideas are developed as a result of this, especially as astrologers explore the other dwarf planets. I must admit I'm most excited about Eris (they finally named it - yay!) and discovering what it will offer to astrological readings.
