@Nekketsu:
Central Pokedex: 37
Coastal Podekex: 30
Mountain Pokedex: 7 and 88 still to reveal. Some of those will surely be new.
! * Dianshii (ディアンシー) — Possibly a deer Pokémon. It’s name could come from deer + fancy + antsy.
- Hariboogu (ハリボーグ) — Most likely the evolution of Chespin — Hari (ハリ) comes from pin/needle, boogu (ボーグ) or bogue, is the name of the shell of a chestnut is French. Thanks to belmad for this tip-off!
- Gekogashira (ゲコガシラ) — Possibly from gecko + boss. Gashira means either head or boss. Possibly a Froakie evolution.
- Borukenion (ボルケニオン) — Probably Volcanyon — likely boruke (ボルケ) from volcano and nion (ニオン) from canyon.
- Dedenne (デデンネ)
- Horubii (ホルビー) — Likely comes from horu (ホル) to dig + bee.
- Nyaonikusu (ニャオニクス) — Probably Meowstick, as mentioned in a previous leak
- Burigaron (ブリガロン) — Maybe a blizzard wolf: buri (ブリ) from blizzard (burizaado) + garo (ガロ / 牙狼) meaning fanged wolf. It could also come from garou (餓狼) meaning starving wolf.
- Jigarude (ジガルデ) — Is possibly from Jiga (ジガ / 自我), which means ego.
- Mafokushii (マフォクシー) — Is possibly an evolution of Fennekin: Mafoxy
- Fuupa (フーパ) — fuu (フー) is most likely wind, pa (パ) could be many things.
- Gekkouga (ゲッコウガ) — Gekkou (ゲッコウ) means moonlight + ga (ガ) is moth. Literally moonlight moth.

- Teerunaa (テールナー) — Possibly related to Gekkouga. Teeru (テール) means tail and runaa (ルナー) means lunar.
There's also a Ground/Ghost and Ground/Fairy pokemon, according to a legit reviewer.

And many of the Pokemon in your spoiler have already been revealed (Horubii is Bunnelby, Burigaron is Chesnaught, Gekkouga is Greninja, Torimian is Furfrou, Teerunaa is Braixen, and Dedenne is… well, Dedenne).
But including the Ground/Ghost and Ground/Fairy Pokemon, you're right, we're already at 70. And those Pokemon could have evolutions, and Noivern could also have (pre-)evolutions.
AND we all know that Gamefreak just can't help itself when it comes to Legendaries, so we're already over 80 Pokemon IMO. I'm thinking that the 90 rumor was true.
