The suns nineth planet?

As poor little Pluto is no-longer considered a planet, I was wondering
if astronomers will now be looking for a full sized planet way beyond
Neptune, as I remember reading over the years articles that say that
the gravitational attraction affecting the orbits of KBO type mini
planets like Pluto cannot come from Neptune, but from a full sized
planet as yet undiscovered laying way out in the outer solar system?
