Chatter coming in from this year's GDC reports Niantic's Pokemon themed ARG has reached 650 million downloads and that Pokemon GO players are well on their way towards Pluto in terms of total waking distance
650 million downloads in an 8 month period are nothing to scoff at but the vague nature of the statistic leaves much to be desired. How many of those are returning users or are those downloads counted for the same device? How many of the downloads translate into active players? How many of those players are actually pouring money into the game?
Pokemon GO has hit 500 million downloads in September, which would mean that only 150 million additional downloads occurred in the 6 months since and that we can officially say the hype is pretty much dead.
