A launch date has been set for the Nintendo Switch version of One Piece: Unlimited World Red Deluxe Edition. We originally only had a tentative September 2017 release window. Now, we know it will appear on September 29, 2017. People in North America will only be able to find it in the Nintendo eShop, while people in Europe could get it digitally or physically.
This means there is only about a one month delay between releases. The digital PlayStation 4 and PC versions of One Piece: Unlimited World Red Deluxe Edition will be launching in North America on August 25, 2017. In Europe, it will be available on the PlayStation 4 and PC.
One Piece: Unlimited World Red is immediately available on the Nintendo 3DS, PlayStation 3, PlayStation Vita, and Nintendo Wii U.
Update: Bandai Namco updated their announcement and said the game will not be coming to Xbox One. This article has been edited accordingly.
