Ditto can now be added to your Pokedex in Pokemon Go
Because Ditto won't look like a Ditto in the wild, Pokemon Go trainers now have an incentive to catch every measly Pidgey whose path they cross. Who cares that you already own 1,457 Pidgey; the next one you encounter could be a Ditto, so you better not let it go by. Once another trainer is lucky enough to snag a Ditto, it will show up on your screen correctly marked as a Ditto.
Pokemon Go players are anxiously awaiting the BIG update rumored to be coming December 7th. 100 new second gen Pokemon will be added along with the ability to hold player vs. player battles and make trades. In addition, the update will add the release of a tier of Legendary Pokemon, and hatching Pokemon eggs will be replaced by the ability to raise Pokemon babies.
