I didn't expect a video today we sure are getting a lot of info this week and then in 4 days the Demo!!
Silvally is clearly been hinted by the official Ability names to be related in some way to Arceus as of now it's because of the Ar/KRS/Alpha system etc... (Depending on what your native language is.) Japanese trailer shows the bag when speaking about it so those are the memories (one for each type not one item for all)
HaKammo-o Is cool and then we have Kommo-o, this last one dex info is some Berserk/Macbeth reference mine gold. It seems now it has a Sound based, Dragon type move that lowers defense (Loses scales) after using it. (like a Narajala i wonder if real snakes do that.) It looks like it's going to be fast from the trailers.
Alola-Muk is so cool I really like the desing now has sharp teeth and sharp claws which go in hand with using Crunch, bite, Poison fang and I'm sure even more. I love how it constantly changes color strats. In the japanese trailer it uses a move I think it is Sludge bomb.
Bonsweet evos are awesome Trop kick seems to be a really decent move as not only deals damage it reduces atk of the opponent. Queenly majesty Ability, nullifies priority moves, doesn't say anything about positive or negative priority so there is that. By the way if you touch the Crown of a Tsareena it loses strength.(That sounds like bait for...).
We got Name, type and abilities of Cutiefly evolution Rimbombee! Don't skip! they have Pollen Puffs!! They have diverse effects! Negative and positives, we don't know if it is an item or a move but it is distributed in Alola at high prices
We got new characters revealed:
Olivia, Specialized in Rock types. Looks really good.
Captain Ilima is the one who manages the Trial with Gumshoos and A-Raticate as he is specialized in normal types and the first Trial.
Mega Kanghaskan apparently got Parental bond nerfed.
Japanese trailer shows the trainer bag, it's got items, medicines, Tm/Hm, key items, Something with a heart shape...(Berries?), and Z-stones.
