According to Damon Baker, Nintendo of America's licensing department senior manager, Nintendo is currently working with Unity Technologies in order to add 3DS support to Unity, a cross-platform development software.
"We've had those discussions and we are definitely looking at that," Baker said. "Our priority was to get the Wii U build [of Unity] up and done and ready. Because we need a test environment for it, it's taken a while for Unity to get finalized on Wii U, so that we can actually test against it. So that has been made available now and that is why we've got all of these [game] candidates waiting in the wings that are just going through the submission process at this point."
Developers for the Wii U can receive a free license to develop with the Unity engine, giving them access to the majority of the console's hardware and software. Baker stated that 17 Wii U games that were developed with the Unity engine have been submitted and should launch "within the next two months."
"And then, we have another fifty that are waiting in the wings, that are coming; so we've got a lot of Unity content on the way," he said.
With the Wii U's Unity integration out of the way, Nintendo can move on to bringing Unity compatibility to other platforms, Baker said, going on to add that Nintendo and "a lot of developers" want to get the most out of the huge install base on the 3DS. Baker and his associate Dan Adelman spoke last year at PAX Prime about Nintendo's eagerness to accommodate indie developers across its platforms. As part of this initiative, Nintendo is planning to bring the open source development software MonoGame Framework to the Wii U, letting developers re-use code their code from other platforms on the Wii U.
