Well, I needed this after a rough weekend, so I'll give my thoughts.
-It looks like the Rockruff forms bit was true, though we didn't get four like that one said. So as of now, the four big leaks are the Riddler, Chinese, Starter Concepts, and the base Bewear leak (I'm really starting to think the later posts are copycats).
-Of the forms, day is my favorite, I do agree it looks a bit basic, but I still think it works very well. I like the wolf design for it, and I do like it has a bit of the majesty that wolfs are known for. Night form, which while I do like it, I also do consider to be the weaker of the two since I was expecting it to be a bit bulkier to better portray the werewolf look and there are some details I would've redone. Still, it's not a bad design, so I'm OK with it and hopefully it'll look better in animation like most of the new Pokémon have (and I'm glad I'm not the only one who immediately thought of Keaton and Velouria when looking at it, it even has Keaton's black and white hair and his transformed state's promoted colors).
-UB02 Beauty definitely looks like the head of Aether, so there's definitely something going on there. Expansion looks very cool, it seems like it'd be the enforcer of the bunch. Also, I do like that they're basing these guys off of deep sea creatures (though Expansion also gives me mosquito vibes), it makes them seem almost Lovecraftian and I love it when games play around with those elements.
-I look forward to seeing what the big deal with Type Null is.
-Not surprised Ash is in Alola and he seems to be heading off alone, as much as things change, some things must stay the same with the anime.
