OK, the trailer. My thoughts.
Thought the first: We got everything I was anticipating and then some- starters, version mascots, and some gameplay footage is what I was expecting. What we got was all that, the region's name, and the exact release dates. Very, very pleased over here.
Thought the second: I LOVE LITTEN. I am picking it. It's decided. Like Tepig and Chespin before it, Litten is the starter of this bunch I took an immediate liking to, and if Tepig and Chespin are any indicators, Litten will not disappoint me as it evolves. Hoping for Fire/Poison, but as long as the evolved forms look as cool as Litten, I'll be fine with anything. Even Fire/Fighting. That's right, I said it.
Thought the third: Those version mascots. Those alone make me lean a little towards Moon, but I'd like to withhold my final judgement until we got a little more insight on version exclusives- Skrelp is pretty much 90% of the reason Y was my main version, after all.
Thought the fourth: The Alola region. Hawaii. Freaking knew it. This is gonna be awesome.
Thought the fifth: Your character shows up in the battle outside of just sending out the Pokémon at the beginning. HELL. YES. Hoping we get to see them actually throw the Poké Ball when trying to catch a wild Pokémon. It'll be awesome
Thought the sixth: ...This year is gonna just
crawl by.
