Shiny Legendaries?

It seems another leak has happened in the APK mine showing shiny version of the three legendary Kanto birds (according to the PokemonGoHub).

The new 0.69.0 update is downloading five new icons in the background:

• Normal and Shiny Lugia

• Shiny Articuno

• Shiny Zapdos

• Shiny Moltres

Please, be aware that these icons are not yet visible anywhere in the game, but you can find them in the encrypted assets that the app downloads on launch. This has been discovered and reported by ZeChrales of PoGODev fame.
