Pluto is "too small to be a planet" by many nowadays, but is considered a planet out of a sense of history. Any planetary system with less mass than Pluto+Charion should, in my opinion, be out of the running for the title of "planet".
The new planet, however, masses more than Pluto does from what I've heard.
