I'm thinking the new Vitality Sensor might be involved. From the sound of it, its a radical idea that Sakurai came up with and Iwata gave Nintendo's full support behind the product. Without Sora the project would have never came to fruitition but without Nintendo's support it also would have failed.
Something that appeals to the hardcore yet radicalizes the market with something new and unique. I can't wait to see it but since its so revolutionary I think Nintendo would likely save such a product for E3!
