A New Pluto?

This was sent to me: http://news.bbc.co.uk/2/hi/science/nature/5344892.stm and it made me wonder. If we were to adopt a ninth "new" planet, how are astrologers going to deal with it? Pluto is the former-planet-now-dwarf-planet that currently rules Scorpio (my sign) and I have a lot personally invested in its "atributes." What if they get reassigned to this up-and-comer?

I don't know if I can cope.
