Pokemon Go UPDATE: Niantic's UNBELIEVABLE new reveal will surprise you
Pokemon Go director John Hanke said that Legendary Pokemon are being treated with care, and will have limitations at Gyms.
Hanke is also said to be excited about PvP battles, which suggests that a release date could be near.
Elsewhere, it was confirmed that Gen 2 Pokemon Smeargle and Delibird were hard to code because of their unique movesets.
Smeargle, for instance, has a move called Sketch, which lets it permanently learn the last move used by its opponent.
Delibird, on the other hand, has a move called Present which either heals or damages the enemy.
Delibird is also associated with Christmas, so it's almost certainly being saved for this year's Christmas event.
