If you are up during the witching hour and have nothing else to do, Nintendo have confirmed that they will be holding one of their Nintendo Direct conferences from midnight (AEST) between today (Wednesday 7th August 2013) and the 8th August 2013. The conference as always will be streamed via the official Nintendo Direct website.
Unfortunately it does not seem like there will be any new announcements made during the events. Instead it will be hosted by Nintendo President Satoru Iwata and Nintendo of Europe President Satoru Shibata as they provide updates for upcoming Wii U and Nintendo 3DS titles.
