If you're ever curious as to what's on the horizon for Pokémon GO, you can always count on random dataminers on Twitter and Reddit to tell you the minute they discover it in new updates. The latest leak comes via Twitter as Leek Duck revealed a pair of screenshots that show off all of the new Shiny Pokémon sprites coming to the game. The info comes from the user known as Charles, who is usually one of the main people on the cusp of finding new materials for Pokémon GO.
Here's a look at all the Shinies added today from Johto (Generation 2). Special Thanks to @Chrales.
Although these were found in the network traffic, it does not mean they are coming to the game soon. pic.twitter.com/1tESTuc7T5

The short version of the leak is that there will be Shiny version of the first 251 Pokémon in the game, but since this isn't official news from Niantic and there's no time-frame on the updates, there's no way of knowing when these will be added. At the very least it means when the next update rolls around there's a pretty good chance we'll be seeing these added to the game, if not at a later date in the near future as a simple addition from the developers.
