premature deplanetation

The act of NASA downgrading Pluto from a planet to a "dwarf planet" (whatever THAT is) prematurely then finding yet another moon orbiting it. The act of premature deplanetation caused all science textbooks and supplemental teaching materials published prior to 2006 to be obsolete. However, with this fourth moon discovery, could Pluto regain it's glory as a full fledged planet?

Joe: Dude, can you believe that Pluto is not a planet? Now I can't teach my kids that mnemonic device "My Very Excellent Mother Just Served Us Nine Pizzas" to learn the planets.

Mike: Don't worry, Bro. I heard NASA is experiencing some premature deplanetation since they discovered Pluto has a fourth moon.
