    2012VP 113; doesn' that mean it was identified in 2012? Why is it just hitting the news now? Could it be related to Brazil's announcement due out today?

    What is more interesting imo is this little snippet from the article:

    Both Sedna and 2012 VP113 were found near their closest approach to the sun, but they both have orbits that go out to hundreds of AU, at which point they would be too faint to discover. The similarity in the orbits found for Sedna, 2012 VP113 and a few other objects near the edge of the Kuiper Belt suggests the new object's orbit might be influenced by the potential presence of a yet unseen planet perhaps up to 10 times the size of Earth. Further studies of this deep space arena will continue.

    They did say it took them a year of observations to pin down the orbital trajectory. I would imagine that 2012 represents the first identification of the object. After that, you have peer review and publishing schedules, so... here we are at 2014.
