The thing about datamining is that it doesn’t always paint a picture of where a game is going; it paints a picture of where the developers considered directing a game. Sometimes there are hints that never wind up going anywhere more substantial. But we can hope that the latest round of datamining for Pokemon Go is accurate, because it points to what would be a huge change for the game with the addition of story quests.
Yes, there are hints about a full quest system complete with a complete rework of the previous daily spin/catch bonuses. Those had always been labeled as quests, but the latest patch adds in several other categories of quests complete with objectives and potential rewards. Obviously, none of this is active in the game at the moment and there’s certainty of when or whether it’ll be rolled out, but the prospect alone should be enticing to fans of the game.
