Nintendo will announce Mario Maker at E3 2014, if a leaked image of marketing material is accurate. The image, obtained by Nintendo Enthusiast, depicts marketing material for the unannounced title. This follows yesterday major leak which contains all of Nintendo's E3 announcements, which can be found here. Evidence suggests the Mario Maker will allow users to create their own 8-bit era Mario levels using a stylus. It's unclear which Nintendo platform the game is intended for. While Nintendo will not deliver a press conference at E3, the company has confirmed it will broadcast four E3 'digital events' during the week.
