Not quite sure what you mean by "already". When Pluto was discovered, it was believed to be quite a lot larger than the size we now know it has. There has therefore been a debate for quite a while already. When a ... planet, planetoid, dwarf planet, or whatever, was discovered (Eris), which was slightly larger than Pluto, the International Astronomical Union decided it was time to clarify what should be called a planet.
