Nintendo's chief game designer Shigeru Miyamoto is more interested in creating new games for Wii U than in recreating HD versions of old games.
Speaking to a panel of reporters earlier this week, he answered a question on the potential for remakes of older games in HD. "That's certainly possible, but most of our developers are working on new games," he said. "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."
Miyamoto was being interviewed about forthcoming platform title Super Mario 3D World, and addressed the game's mixture of new ideas and inspirations from past Nintendo games. "If your interest is in finding elements from previous games you'll find them scattered all about," he said. "There is a lot of content like that."
He said that the game melded together the best of 2D and 3D game design, but that a full 3D game might be possible in the future. "We've tried to find some fun new elements that we could incorporate. I certainly wouldn't rule out the possibility of us creating more games like [Super Mario Galaxy] in the future. What we're trying to accomplish here is to create a good entry point for new players."
