Updated 09/03/2018: Sadly, there’s a possibility that the Detective Pikachu demo will only be made available in Japan. We’ll let you know if this changes in the future!
A new English trailer has been published for the upcoming 3DS title Detective Pikachu. Take look at the trailer below!
While the UK version of the trailer only showcases the game's release date and the special Detective Pikachu Amiibo, the North American trailer also highlights a promotion for a free Detective Pikachu 3DS Theme - presumably implying that the promotion is North American only.
As detailed on Nintendo.com, if you pre-order Detective Pikachu from the 3DS eShop or Nintendo.com (starting March 3rd at 9:00am PST) or starting March 23rd purchase it digitally/physically on the 3DS eShop, Nintendo.com, or from select retailers, you'll receive a bonus code for the 3DS theme. This offer ends on April 22nd, 2018, and the codes must be redeemed by December 31st, 2018.
We've also learned that a demo for Detective Pikachu will be available via the 3DS eShop at some point in early March (date currently unknown). If you download and play through the demo you'll later be able to transfer your save data to the full version of the game.
This retail version of Detective Pikachu releases worldwide March 23rd, 2018. In the meantime, we'll let you know if more information crops up for it!
