The main conflict throughout the franchise so far, is about Po learning and becoming the Dragon warrior. From Kung Fu Panda 1-3 Po learns many different things, from inner peace, to the power of chi, all at the same time defending China with the help of the Furious Five and his master, Shifu. All of this leads up to him, finding his true power from within. It is likely that there will be more movies to the Kung Fu Panda franchise, although it is unknown about what, conflict will preceded.
