Could there be a factual basis for Nibiru?

For those not familiar with the concept of a planet called Nibiru, here is a basic explanation.  Nibiru is popular among 2012 doomsday hypotheses but is mostly relegated to the realm of pseudoscience and conspiracy theory.  Some new research may confirm the existence of a large object on the very fringes of our solar system though.

Could this proposed planet, Tyche, be the planet Nibiru hypothesized by Zecharia Sitchin as the home of the Anunnaki?  If nothing else it is potentially an exciting find that I'm sure will have many of the Nibiru believers pointing and saying "I told you so!"
