John Hanke, the head of Niantic Labs, revealed more to come for Pokémon GO as he spoke at the San Diego Comic-Con Pokémon Panel, according to IGN.
Hanke revealed that over the coming months we could see more Pokémon coming, although he did not give a specific time-frame for the addition of the next generations.
He did, however, confirm that trading is in development, but there is also no planned release date for the feature at this time. Hanke said that, at this point, the top priority is keeping the servers up and running.
Pokémon Centers are more of an idea at the moment, but Hanke also said that Niantic is working on PokéStop customization so players can build up areas and use items to change the use of a PokéStop.
Also revealed at the panel were the full images of the team leaders, which up to this point have been just silhouettes.
Team Valor is headed by Candela, Team Mystic by Blanche and Team Instinct (the best team) is headed by Spark.
