My feeling on the matter is what complicated things is when a new body 2003 UB313 needed to be classified and it was remarkably Pluto like (larger even).

The truth is that the first definition the the IAU commitee came up with is how I will always think of the definition of a planet which include Pluto and the other bodies as plutons (a name that I have fallen in love with). So congradulations we know have a 12 planet system in our eyes if no one elses.
