It looks like players will have an opportunity to capture an ultra-rare version of the already rare Pokemon Mew in Pokemon Go. A dataminer has reported that Pokemon Go developers have added 3D assets for a Shiny version of Mew onto the game's servers. Mew will officially be added to the game tomorrow as part of a major update that includes "Field Research" quests. Prior to Halloween 2017, Pokemon Go only had Shiny versions of the Pikachu and Magikarp families of Pokemon.
