When Pokemon GO first launched, it did so with most of the Generation 1 Pokemon, minus Legendary Pokemon and some select others. Since then, Niantic has greatly expanded the number of Pokemon in Pokemon GO, introducing creatures from the Johto region all the way to the sixth generation of Pokemon games. Gen 6 Pokemon were added to Pokemon GO in December 2020, meaning it's been well over a year since the popular mobile game has had a significant influx of new creatures to catch. But now there's evidence to suggest that a slew of new Pokemon could be on the way sooner rather than later.
