No More Planet Pluto

Pluto demoted under new definition of planet

Definition of a planet - "a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a … nearly round shape, and has cleared the neighbourhood around its orbit."

The article goes on to say that "Pluto doesn't qualify because its orbit is inclined relative to the rest of the solar system and crosses over the orbit of Neptune."

I'm not really sure how to take this. I think they could leave Pluto in, but anything discovered afterwards that did not fit the definition would not be.

Any thoughts?
