The Swedish site Loading
claims to have information about the next Nintendo console, specifically its mythical, gigantic touchscreen control device
. The "Nintendo Feel," as Loading's source calls it, has a controller whose touchscreen provides haptic feedback -- it can change the texture of areas of the screen to provide touch-based feedback in response to onscreen events.
phone-size screens are available with this technology, so it's not quite science fiction. And it would fulfill the "bizarre left-field technology that Nintendo pushes" requirement of every recent Nintendo console. But regardless, this is a rumor on top of a rumor about something we really don't know much about.
