Now we’re not sure when the trading or player versus player battles are going to be introduced (hopefully soon), but in the meantime it seems that there is yet another potential feature of the game that Niantic appears to working on. This is according to a post on Reddit in which code has been discovered that makes reference to some kind of “Buddy System”.
According to the data mining of the game, it mentions some kind of buddy function in which one of your Pokemon would be able to follow you around and register the distance travelled the same way as an incubated egg. From there and based on the distance travelled, the Pokemon will then be able to grant “Buddy Candies”.
While it is unclear as to how this will work, it has been speculated that this will allow players to generate specific candies when walking around with a specific Pokemon. There is also no word on when Niantic plans on introducing this feature to the game, but we’ll keep an eye out for it.
