If Pokemon Go is currently a bit lacking in novelties, the latter all seem to be in the source code of the game, which contains a plethora of them. Impossible to know when they will arrive, but they are there!
Pokemon Go has been turning a bit in circles for a few weeks, the fault to a lack of novelty that is beginning to be felt. What do you do when you are a seasoned player and you have already been able to achieve all the objectives given by the game? For example, what to do after completing the pokedex? There is still something to be done while waiting for the new products, it is certain, especially since we know that they are coming, these novelties. In the source code of the game, minor data could find all the features that we know will happen in Pokemon Go, without being implemented until today by Niantic . No doubt then that Niantic keeps these novelties for later, remains to be seen when they will be added to the game. Meanwhile, here is the lite of things that are confirmed as being already in the game!
First, objects : The Master Ball, buffs attack, defense and an object titled “Miracle”. New bays are also in the game: Remu Bay, Nanab Bay, Repoi Bay and Nanana Bay will be added to Pokemon Go.

Pokemon natures have been added to the game: Stoic, Assassin, Guardian, Protector, Champion … Finally, the exchanges are also part of the novelties that are already in the code of the game without being part of the features already available in Pokemon Go. The categories for exchanges have been divided as follows: it will be possible to “search”, “offer”, “reply” or “give the result” of an exchange! In short, we know that the second generation of Pokemon is already in the game , remains to be seen if other features like reproduction for example will really make their appearance in Pokemon Go !
