I think that this will be the system used, mostly so that it's easier for trainers to "spot" you and initiate a battle. There's really no evidence in the video though. I don't think the sharp left turn in the forest really proves or disproves either theory. Onto my hopes, the following list is of unused pokemon type combinations and why I think they haven't been made yet: Electric/ Rock - I was actually hoping to find one of these in Chargestone Cave, oh well Fire/ Ice - kind of polar opposites in the pokemon world, but then again we do have a psychic fighting Dragon/ Poison - because GF hates poison types Electric/ Poison - see above Dark/Psychic - this one is baffling, it seems like we would have already had one of these Psychic/ Ghost - same thing as above Electric/ Dark - again, same thing as above Bug/ Ice - bugs don't like to live in the cold (unless they used the colloquial term bug for sickness and made an ice virus called the common cold) I think the most likely combination we'll see in the new gen is Electric/Dark. I was really surprised when I discovered this and at first didn't believe it, thinking Luxray was Electric/Dark (it should have been =/). The other ones seem kind of Farfetch'd (wishing for an evo).
