It would appear that Gen 3 monsters will be unleashed as part of Pokémon GO's upcoming Halloween event.

The evidence is two leaks, the first of which is an image found in data files for the game. A piece of artwork - presumably the loading screen art - clearly shows Gen 3 monsters Duskull, Dusknoir, Shuppet, Sableye and Banette.

The second leak is Apple's doing; an image showing Gen 3 Pokémon - as well as a witch hat-wearing Pikachu - has been spotted on the iOS App Store. The Pikachu will presumably be a time-limited offering, as has been the case previously.

While we've yet to hear any official confirmation that Gen 3 is coming this Halloween, these two leaks would suggest it's almost certainly on the cards.
