The developers have been at work thinking of new concepts, creating them, and implementing them to the MILLIONS of players around the WORLD. It takes time to do that stuff. Im sure theyll eventually get around to implementing all the stuff most people are complaining PoGo needs, everyone just needs to chill. Its kind of a good thing theyre taking a while, cause itll get rid of all the fake players that never even cared for Pokémon to begin with. Only true fans of the game with a prior knowledge and appreciation for the game end up staying anyway, mostly.
