Yes that's right, my dad who TOTALLY WORKS AT GAMEFREAK has TOTALLY told me that Gamefreak are going to be announcing Pokémon XXX and YYY Versions. These versions, abbreviated to XY3, are said to feature a 3-3-3 policy.
1) Three times as many gyms 2) Three times more map 3) Three times as much endgame
Also, I heard a rumour that all Pokémon will be available (including non-event legendaries!) with their hidden abilities.
Rumour has it that Sasha Grey is voicing the female protagonist.
