According to an "insider", a report on Develop is claiming that Nintendo's next home console will ship with a controller that features a front-facing camera. Just like the DSi and 3DS.
This camera would "be used for in-game images"; presumably, that means anything you take a snap of (like you face) could be then imported into a game.
If correct, this would mean that the console's controller would feature a touch-screen display and a camera in addition to the regular stuff like buttons.
So it's a DSi, then!
