The Switch can claim yet another victory when it comes to Wii U ports. New Super Mario Bros. U's launch week sales in Japan came in at 163,582 units sold back in 2012. New Super Mario Bros. U Deluxe has had its first week in Japan, and total sales came out to be 166,303 units. We're comparing NSMBU, which was a launch game on Wii U, to NSMBUD, which has received little promotion and came out after the holiday season. Once again, we see Nintendo's approach to select Wii U ports continues to pay off!
