Generation Four Pokémon teased in Pokémon GO image

The Sinnoh Starters have been spotted for the first time!

The official Pokémon GO Twitter account has made a tweet today asking trainers about their memorable experiences. The tweet was accompanied with a picture, which may have distracted respondents from answering the question.

Located by the Absol, Gardevoir and camper shade are the three Sinnoh Starter Pokémon: Piplup, Turtwig and Chimchar. This is the first clear hint towards generation four Pokémon in Pokémon GO! Might we see them pop up in the coming months?

Thanks to Erik for the tip.
