So far, only two new Pokemon have been revealed, both of them featuring in the 13th movie. Their names are Zorua and Zoroark (I think I spelt them right...) and both are the dark type. Zorua is an evil fox Pokemon while Zoroark is a monster fox Pokemon. From the 13th movie, it appears that Zoroark can change it's form, so maybe one of it's moves will be transform?
According to CoroCoro, the camera angle that we have become so used to has been changed to one that will show more of your surrondings and will appear more 3D than ever before. Also it appears that there is a Pokemart within a Pokemon Centre. Whether this is true for all Pokemarts is yet to be seen. Also, it appears that the battle screen camera has changed too.
Anyway, I recommend checking out this link -
