The nine planet system was doomed after 2003 UB313 was discovered and found to be larger Pluto. So if UB313 is not a planet then Pluto cannot still be a planet. However, if Pluto is a planet then surely 2003 UB313 is a planet as well. What seems to have complicated the debate is that some astronomers vehemently want to demote totally as a planet; for them even 'dwarf planet' status doesn't go far enough. On the other hand there are other people who just a vehemently want to keep Pluto as planet.
I doubt this IAU meeting will be the final word on the question in the long run.
