Something to note here from ElChicoEevee (typically datamines Pokemon Unite and various models from games, so has a fair amount of credibility);
12 slots have been found and we only know about 8(?) so far (4 Paradox, Peach, Terapagos, Archaludon, Applin4) so that means 4 potential new Pokémon?
Formes are apparently counted differently.
Personally, I don't think this means 4 new Pokémon, it probably is just due to models and Eevee is mistaken, or misunderstanding.
and I can't imagine Khu would pass up the opportunity to relish in the attention.
But hey! It creates some genuine datamine-based conversation until Thursday.
