An Amazon.com product listing for the Pokémon X and Pokémon Y official strategy guide has leaked the existence of an as yet unannounced feature.
Alongside already confirmed additions, such as Sky Battles, Horde Encounters, and Pokémon-Amie, it also mentions Super Training, although fails to reveal any further information.
We’re sure to learn more in the coming weeks, although the news has kicked the Internet into a frenzy of speculation.
Those interested in purchasing the official guide can also look forward to a Pokémon screen cleaner, and a pull-out Kalos region map.
