NIBIRU, TYCHE, NEMESIS

This story has hit the various news outlets but in a rather subdued manner.

We may have lost Pluto, but it looks like we might be getting Tyche.
Scientists may soon be able to prove the existence of the gas giant, which could be four times the size of Jupiter, according to astrophysicists John Matese and Daniel Whitmire from the University of Louisiana at Lafayette. The two first proposed Tyche's existence in order to explain a change in path of comets entering the solar system...
So how could we have missed such a massive planet in our own solar system?
Well, it's 15,000 times further from the sun than Earth, according to Gizmodo. Tyche (if it does exist) lies in the Oort cloud, the outer shell of asteroids in our solar system.
If we've missed a planet in our own solar system for this long, what else are we missing?

Nibiru, in Babylonian Astronomy translates to "Planet of Crossing" or "Point of Transition", especially of rivers, i.e. river crossings or ferry-boats, a term of the highest point of the ecliptic, i.e. the point of summer solstice, and its associated constellation. The establishment of the Nibiru point is described in tablet 5 of the Enuma Elish. Its cuneiform sign was often a cross, or various winged disc. The Sumerian culture was located in the fertile lands between the Euphrates and Tigris rivers, at the southern part of today's Iraq. As the highest point in the paths of the planets, Nibiru was considered the seat of the summus deus who pastures the stars like sheep, in Babylon identified with Marduk. This interpretation of Marduk as the ruler of the cosmos was identified as an early monotheist tendency in Babylonian religion by Alfred Jeremias.
Some authors believe that the observations of ancient astronomers provide proof that Nibiru is an actual planet or brown dwarf in our solar system. These claims are for the most part dismissed as fringe science or pseudoscience by the mainstream scientific communities of archaeology and astronomy.
The work of Zecharia Sitchin has garnered much attention among ufologists, ancient astronaut theorists and conspiracy theorists. He claims to have uncovered, through his retranslations of Sumerian texts, evidence that the human race was visited by a group of extraterrestrials from a distant planet in our own Solar System.

 SO THE BIG QUESTION: Is Tyche and Nibiru one and the same? They are in the same position. 

Further, what does it mean that is is now in a place that can be observed.? Is this also the ancient planet called Nemesis? Is this all coincidence as we approach 2012 or is it synchronicity?
