The name for the tenth planet still has not been confirmed. There has been speculation surrounding both Lila and Xena as possible names, but according to Michael Brown neither of those names has been chosen.
For years, many astrologers have said that when a planet is discovered beyond Pluto it will be named PanHorus. Based on what I've been reading about the planet, it seems like there's a good chance that either Pan or Horus will be chosen as the name. Not sure if both names will be chosen, though. We shall see.
Meanwhile, astro.com has a provisional ephemeris up on their site for the tenth planet.
