We just had a new trailer revealed a day ago.  We saw the new Starters as well as the Cover Legendary Pokémon.  However, one thing that's rather curious is that we did not get the official names or typings for the new Cover Legendary Pokémon.  Based on a previous leak, I've been calling them by their leaked names Solgaleo, the Cover Legendary of Pokémon Sun, and Lunaala, the Cover Legendary of Pokémon Moon, respectively.  With that said, I'm predicting that both Solgaleo and Lunaala will be a new type as it would both explain why they weren't revealed by name or type in the new trailer.  Of course I could just be overthinking this and I'm a guy who thought that Zekrom was going to be Dark/Dragon and thought a leak of Echo type was legitmate way back when so obviously take this with a grain of salt.  I'm just sharing my thoughts.  Any thoughts on a new type coming with Solgaleo possibly being a New type/Fire-type Pokémon and Lunaala being a New type/Flying-type Pokémon?

Too soon, I think. Introducing a new type is a fast way of balancing the game. In gen 2 steel and dark could counter psychic really well, and in gen 6 fairy type counters dragon while buffing poison. Right now, there is no single type that is clearly overpowered, so there is no need for a new type.

This. No need for a new type. Things are balanced at the moment. They've only introduced new types when they were necessary. Adding one now would unbalance the game potentially. The only benefit is that it COULD make Normal finally have something its strong against

I'm pretty sure that the primary reason Fairy types were added last gen were to help balance out certain types, mainly dragon types, and was pretty much like when they added Steel in Gen 2 to help balancing.

From what I've seen, everything is fine for now, and until a certain type starts to become ridiculously powerful again, we probably won't see a new type anytime soon.

Imho there's no need for other types, they only need to balance out the types they now have *hint hint Water and Fairy*. Imho Solgaleo COULD have a new type (type light ?) but Lunaala is 100% Ghost/Flying, it has bones and it flies, you can't co further than that...

If balance is what you want, we need a complete base stat revamp, not a new type. As of now competitive game is very thin and the number of pokemon actually used is very small. Because really, the rest suck. We need a balance to that.

Nah, at most they'll have balance changes, namely buffing Grass and Ice now that Poison n Steel type moves are more common. Seriously Ice only resisting itself is dumb, should also resist Dragon, Ground, and Water I say.

Agreed, Water should get nerfed and Ice resisting it is a great start...
