Developers working on Wii U projects have counted the Unity engine among their options since last year, but support for Unity is still absent from the 3DS. Considering more than 42 million 3DS units have been sold worldwide, in comparison to the 5.86 million Wii U shipped to retailers as of January, Unity's absence from the 3DS is puzzling. Siliconera asked Nintendo's Senior Manager of Marketing Damon Baker about Unity's absence from the 3DS during GDC, learning that the company is considering implementing support for the handheld as well.
While Baker noted there was nothing to announce at this time concerning Unity support for the 3DS, he stated that Nintendo is "definitely looking at that." Baker explained that getting the Unity situation sorted out on the Wii U was Nintendo's priority, adding that it can now focus on expanding compatibility for other platforms, "either with Unity or with additional middleware providers as well."
Unity support was added to Sony's Vita in January, so doing the same with the 3DS would feel like a logical move if Nintendo wants to stay competitive as a host of developer-friendly platforms.
