I cannot answer that question as I have no basis, one way or the other, of knowing if it was ever in our skies before, so as to have an opinion on whether as to whether it will ever return,
Someone else was asking what will happen when it returns in 2012, recently. I commented that it was a remarkable coincidence that Babylonian mythology and Mayan mythology both came up with the same doomsday date, when neither civilisation knew of the other's existence. separated as they were by the Atlantic Ocean, with no ocean-going liners and with no satellite communications. An almost uncanny coincidence, I suggested.
By which I meant that it looked like Nibiru mystics were jumping on the bandwagon of the Mayan 2012 prophecy.
One has to start from the premise that to date only comets penetrate to the Inner Solar System from the region of the Oort Cloud and no planets are known to do that. The gravitational pull of Jupiter would seem too great.
I would need convincing that a planet could follow an orbit that brought it close to earth at perihelion and go out beyond Pluto and Eris at aphelion. and that it would not be affected by any of the four gas giants as it headed inwards to the Sun.
Sedna has a 12,050 year orbit which varies between 975 AU at aphelion in the Oort Cloud and 76 AU at perihelion and a semi-major axis of 525 AU. But it doesn't even cross within Pluto's orbit, let alone Neptune's. i.e. it comes a long way in from a long way out but it remains firmly a Trans-Neptunian Object. One is bound to ask why Nibiru should be any different?
I have heard the thesis advanced that Nibiru enters our Solar System from outside of it and leaves it again. I just find that too difficult to believe: where does it go? What gravitational force takes it there? What gravitational force wrenches it back every 3,600 years? It can't be the nearest star (Proxima Centauri) tugging on it as 4.22 light years is 266,877 AU years away and gravity is an inverse-square law!
So I think we can discount that possibility, which leaves us with an improbable and hazardous journey from the Oort Cloud to the Inner Solar System. The fate of Comet Shoemaker-Levy 9. crashing into Jupiter in 1994 suggests what could so easily happen to celestial objects that wander too close to the giant Jovian planets.
I think this whole matter can only be settled by there being some definite sightings of Nibiru, and its orbit being calculated from these observations. I have to say, though, "Where is it?" if it is supposed to be here in 2012? It will have to start showing its face soon as the speed needed to get here from Pluto in under 4 and a half years would have to be more than twice that of the New Horizons probe (65,000 mph) which will take 9 years to get from Earth to Pluto (launched Jan 2006, ETA: July 2015) and one wonders how it will manage to get up to speed as Pluto's maximum orbital speed is a mere 13,750 mph and I am suggesting Nibiru if it emerged in Pluto's backyard tomorrow would need 130,000 mph to be able to rendezvous with earth in 2012!
It does seem a little unlikely, doesn't it?

I'd say if it is coming the powers to be will make sure no one knows about it! The reason I would say it is coming is because nothing makes any since to me any more. Starting with the masses denial that the environment supports all life systems on the this planet.If the truth be known this planet is dying fast!

Not many I presume, since it flies in the face of the DNA evidence which shows that we are genetically apes, and share our DNA and RNA with every other living creature on Earth.
There is no evidence, other than anecdotal or tribal mythology, that there has ever been implanted DNA in our genes.
