So apparently, the same guy who did this has put out another I guess "leak" (although I'm not believing it until we see some new trailers or whatever) and these are what he said will be in the game. I couldn't find the pic so I'm just writing it down from the video I saw. Btw, anything written in parenthesis is me thinking what this could mean.
Exscalebur and Trojallant both are part Steel types (I'm guessing these are the assumed legendaries he's talking about)
Team Magic are literally angry wizards (Evil Team?)
There are 11 different Ancient Armors (I have NO clue what this could mean but it has me curious)
Mewtwo, Charizard and Zeraora each have Armored Sword and Armored Shield version exclusive evolution (Sooo… we're gonna get Charizard with a Sword or Shield? Lol.)
There are only 64 new Pokemon (This would be kind of a huge bummer if proven right but I'm just happy for a new game so I can live with this if it's true)
3 new eeveelutions (This 1 I'm actually hoping is true. The last 1 we got was Sylveon and that was like 6/7 years ago?)
So that's everything the guy had said would be in the game. What do you all think? For me, I'm kind of hoping that there are more than 64 new Pokemon. But if not, I can still live with it. But I'd definitely be down for more eeveelutions. And if there are to be 3 guaranteed in this game, no doubt Steel and Dragon would claim 2 of those spots but the last 1 I would feel would either be Rock, Ground or Ghost.
