In January, we reported that Nintendo was planning on moving into the mobile space, but not with its back catalog. At the year-end investor briefing, the company has shared additional details about what that will look like.
According to analyst David Gibson, who is attending the briefing, the company will release a mobile app that pairs with Mario Kart 8. The Mario Kart TV app will be able to access saved highlight videos and rankings. Release is planned before the end of the current fiscal year (March 31, 2015).
