Super Mario World HD? Super Mario 64 HD? Such things could happen, according to Nintendo design boss Shigeru Miyamoto.
"That's certainly possible,” he told a reporter panel attended by Polygon when asked if Mario HD remakes are being considered. But most of our developers are working on new games. We like to have them working on new stuff.
HD remakes might be a good project for development partners, so that's something I hope we can introduce in the future."
Nintendo has never been afraid of repackaging and reselling its old software, and the recent release of The Legend of Zelda: Wind Waker HD on Wii U shows that the company is at least open to the idea of a visual overhaul for older software.
