Planetary science will not change with any change in definition, or what objects that orbit the sun we put in what boxes. To restate it, I don't know of any predictive or descriptive difference beteween the 8 or the 14+ planet cases. Both cases describe the same solar system; they just attribute different words to different sets of circumstances.
