Welcome to the KoTOR III forum, Bastila_Shan.
There's quite a bit of speculation running rampant about the possibility of a third installment to the series. Since nothing has been announced at this time, that's all it is, sadly.
Since you're new to the forum, I recommend that you browse the threads posted here, since as I stated earlier, speculation is dripping off the walls.
Feel free to join in any of them if you feel you have something to contribute. Since there's already a number of threads here about this very topic, I'll close this one.
