In regards to Eeveelutions. If I wanted one for this new Gen, I'd want a Steel one.
Leafeon gets countered by Glaceon, Espeon gets countered by Umbreon. I'm just so used to the pattern I'm surprised Sylveon didn't get a counter to balance it.
So the next one I can see would be either Steel or Poison. Dragon is wanted but I feel like that can just come later. I'm not saying the pattern should continue, as Pokemon has broken patterns before, but I wouldn't mind something to counter Sylveon in the Eeveelution circle.
Dragon was a requested one, but I think with time, people felt that the Dragon-type was intentionally overpowered and that a Dragon-type Eeveelution would be similarly overpowered. Things are different now with the addition of the Fairy-type; now it wouldn't feel so overpowered, though the type still has a sort of special feel to it (even if you have relatively mundane Pokémon given the Dragon-type, like Altaria and Dragalge).
With Gigantamax retro fat pikachu & long cat meowth being leaked from corocoro. We now have more evidence for the credible leak.
Makes me wonder just how many Gigantamax-capable Pokémon species there are. Seems like there will be a lot of them.
Charizard's also the first one revealed to have previously had a Mega Evolution (and no doubt Leon will Gigantamax his Charizard). Makes me wonder if Mega Evolutions were nixed because they turned out to be TOO good (some of them, at least), creating game balance disasters like Mega Mawile, Mega Gengar, and Mega Kangaskhan, and that Gigantamax is its replacement--namely that Pokémon that still need a boost might still get a Gigantamax form, like Lopunny and Beedrill.
If this is true, I can imagine there will be a lot of outrage that this is some inferior replacement, even if their Gigantamax forms look identical to their Mega Evolutions in every way.
I'm still not entirely sure what Gigantamax actually does that's different than regular Dynamax though.
