Or if there were we'd already have found them?

Pluto is actually being declassified as a planet because of a thing called the Kuiper Belt which is around our solar system. The Kuiper Belt is a huge ring (like the rings of Saturn except around our ENTIRE solar system) containing comet candidates and asteroids. Pluto is believed to be a Kuiper Belt Object since its orbit isnt like the rest of our planets. There are other Kuiper Belt objects LARGER than pluto wich aren't called planets and even the Hubble Telescope cannot count them all. Objects like Quarar and Sedna could be considered in the same class as Pluto. We have a probe on its way ( In think by 2015) that will tell us more about pluto and maybe even some other ojects out at Pluto's distance.

In our solar system there is a very high probability that there are more dwarf planets that have yet to be discovered. The Kuiper Belt contains many millions or even billions of objects, yet less than a thousand of these have been observed. That aside, there have been three other discoveries of dwarf planets- UB313 (nicknamed Xena temporarily, now Eris), Sedna, and Ceres (an asteroid).

Ones big enough to fit the newly revised definition of a planet...doubtful. But "dwarf planets" nearly or as big as Pluto? Probably. One was discovered as recently as 2003, and nobody's been looking until recently, so there's a very good chance we'll find more.
These bodies aren't large enough to "predict" their existence through their gravitational interaction with other planets...which is how Neptune and Pluto (sort of) were found. Since they're so far from the sun, they're also quite dim. Finding them will take dedicated sky surveys, imaging the same part of the sky over and over again, looking for things that move. It'll take some time, but we'll probably find some.

yes, and we have found em...3 of em i think. Its just that most people have stopeed reading newspapers and stuff but yes there are more planets than Pluto.

If there were, either the Hubble telescope or one of our probes would have seen them. Pluto is the outer limit of this system.

well, you never know. like we`ve recently found out, pluto isn`t actually a planet. its an asteroid. it shows how vast our galaxy is and how there`s so much more to explore.

I think not, as after that it is just a very large belt of rock and ice that is left over from the building of our sola system.

Yes. One such dwarf planet was named "Sedna" and was recently discovered.

No. It has been proven that there are not any more planets in our solar system.
