Pokémon Go is getting new Pokémon, info coming on December 12

Pokémon Go is getting ready for its biggest update ever.

Niantic and the Pokémon company announced in a short release sent to GamesBeat that more creatures are coming to its location-based mobile game, with details coming on December 12. Pokémon Go is one of the most popular mobile games of all time, and a big update adding more pocket monsters could revive — and for others, sustain — interest in the app. The game has generated more than 500 million downloads and an estimated $600 million in revenues in its first 90 days after its launch in July.
