Where is it?
If their modelling has revealed that this planet should exist in a wildly eccentric orbit way off the normal ecliptic plane, based on the perturbations to Kuiper Belt objects, surely it has also predicted, fairly specifically (in astronomical terms at any rate) whereabouts in its orbit it needed to be to cause those disturbances, so they should have a reasonable clue whereabouts it ought to be to start looking?
