What would be the propable trajectory and position of the ninth planet that has been suggested few days ago (20.1.2016 by Konstantin Batygin and Michael E. Brown) ?

if i understood correctly, the exact position of the planet is unknown and has not been evaluated.

But by looking this article http://iopscience.iop.org/article/10.3847/0004-6256/151/2/22/pdf

the orbital elements and physical properties they used in one of their simulation looks like to be (page 9 second column)

[itex] m > 10 m_{earth} [/itex] mass

[itex] i = 30 ° [/itex] inclination, this would mean that the estimated trajectory is a great circle that is in the 30° angle to the celestial equator. But i dont know what is the direction of the perihelion, aphelion or ascending node?

[itex] e = 0.6 [/itex] eccentricity

[itex] a = 700 Au , b = 550 Au [/itex] semimajor axis and semiminor axis

[itex] ω = 150 ° [/itex] argument of perihelion (from what direction?)

but i dont know how to estimate error limits. Also the discussion section says that the analysis is not yet complete and other possibilities may not be excluded.
