One player has managed to decipher the code from the latest update which seems to allude to the ability to trade Pokemon.
It appears that a core aspect of the original Pokemon gaming series could be making it's way to Pokemon Go sooner rather than later,
A reddit user has broken down the code from the most recent update, and four of the many variables found allude to the ability to trade pokemon.
Trade_search <- you can search for people looking to trade?
Trade_offer <- offer a trade to someone that wants to trade?
Trade_response <- when you offer a trade, they respond with whether or not they will go through with it?
Trade_result <- after an interaction, what happens, who gets what.
So it seems that trading has already been implemented, it's just a matter of when to release for Niantic. Check the official discussion to see more of the codes that were released.
Trading Pokemon has been one of the most highly suggested features that players would like implemented in one of the augmented-reality game's next updates. Not only would it help virtual trainers in building up their line-up by trading away some of their lesser Pokemon, trading would also allow for those looking to catch 'em all the ability to trade with foreign players for the region-locked Pokemon without traveling overseas.
Currently, there are four region locked Pokemon which can only be found in their respective locations: Taurus in North America, Farfetch'd in Japan, Kangaskhan in Australia, and Mr. Mime in Europe. Trading will likely certainly spawn all types of different message boards in order to help players trade with one another.
Trading will certainly change the game in a drastic way. What are your thoughts on trainers being able to trade Pokemon?
