It's probably gonna be Scizor, because of the data in the patch.
I agree out of the three pokemon data mined I hope it is scizor just because of the lack of bug pokemon in the game. This applies to both the playable pokemon and support pokemon, there is just no bug representation at all, which is odd since either scizor or heracross or perfect pokemon to play in the game, plus I am sure a bug type could have been chosen for a support role at the very least. The same can be applied for rock types as well, I see a rock type pokemon leaning more on the support side, unless the creators work a playable pokemon side really well, in which guess the fighter would have to be a power type.
I know this thread is hardly looked at but I was just wondering what pokemon everyone still wished entered the game and the choices had to be one pokemon per region. I say one per region just to give the balance to each generation, and I know this probably won't happen, but if the game becomes a franchise then I can see these pokemon being new possibilities. My choices would be:
Kanto: Nidoking- I can see Nidoking being a power type fighter, and give poison types a better representation, since I feel Gengar leans more towards the ghost type, then balance both ghost and poison.
Jhoto: Ursaring- Ursaring will be a standard fighter, and my reasoning is simply to give normal types a rep. in the game, plus Ursaring can be considered a powerful pokemon, especially for normal types.
Hoenn: Claydol- Indeed a random choice, but since chandelure made it in then any pokemon is up for grabs. Claydol I would consider a technical fighter with a balance of moves between ground and psychic.
Sinnoh: Electivire- Electivire would be a standard fighter and give player's an extra electric type that is not pikachu. Electivire has a vast move pool of punches, as well as, distance attacks that could make it a threat up close and far away.
Unova: Zoroark-This choice is mainly based on seeing the match up of zoroark versus lucario. Definitely a standard fighter more distance attacks over close combat attacks.
Kalos: Noivern- Noivern would fall under the speed fighting catergory. Similar to electivire, Noivern would be a threat up close and afar, except its attacks will be a bit weaker then electivire, but makes up for it with the speed of the numerous moves it will be able to produce.
