Pokémon Go updates are often leaked ahead of time through data mines, but the next potential upgrade arrived in the form of a photo. An official tweet from July 22 seems to hint at a new category of Pokémon heading to the game in the near future.

The message seems innocuous, as does the picture, embedded below. Niantic posed a question to players about the recently added trading component, and the photo seems like an illustrative tool to highlight that; it’s of two hands, each holding a cell phone that has the game open. The pair have just completed a trade, with one getting a Pikachu, the other a Chansey.
