The exact date is 15th November, with both games releasing simultaneously worldwide.
That's not all, though. As it was also confirmed that both games will be releasing in a special double pack. If you're keen on buying both versions, this bundle could well be a great option to do just that. More details on this special pack will be released at a later date.
Interestingly, the UK version of the Pokémon Direct showed a slightly different bundle.
What did you think of the Direct? If you're interested, pre-orders have already started to go live.
