I never really agreed with the demotion of Pluto to a 'dwarf' planet back in 2006. It felt to me that the astrophysicists and astronomers and such were in need of something to do, and interested in making news.
I found this article interesting, especially reasserting that Pluto has objects orbiting it and is layered/structured much like Earth.

Holding my breath, waiting for a reversion any time soon, would be foolish. But I suspect in a decade or so, those that decided upon the demotion will reinstate Pluto to full 'planethood." It'll be something to do and will make the news.
