>>27497461Those are two separate leaks.
One claimed regional Alola forms would be a thing (but got Ninetales typing wrong) and also mentioned a bird with 4 forms, which was correct. It did not mention separate starter evos.
The second leak talked about alola specific "colors and markings" and sizes, but failed to mention anything about typings or drastic visual changes. This was the leak that talked about starter evos, but so far it looks like it was just a lucky guess and I wouldn't jump they gun yet.
