So far we have seen Forest area as that is what was displayed in the starters battles and also a bit of overworld roaming along with the trainers. The vine swinging and spider web seem to indicate there is a strong Grass/Bug/Poison presence not to mention Xerneas appeared out of a Forest. There was a arid looking area with a complex in the back ground some maybe there is a city/factory something so Ground/Rock/Steel. Then the urban French feel to it says Normal type to me. At this point who knows but I personal favor more Ghost types since it is the smallest Type group in the game.
