Nintendo has confirmed two Nintendo Direct events for tomorrow. The first event will take place at 4am PDT (7am EDT), and you can click here to watch it. The second event, which will focus on upcoming 3DS games, will take place at 7am PDT (10am EDT). You can click here to convert the time zones.
EDIT: I made a mistake when listing the time the events would start. I’ve added the correct times into the post. Sorry for any inconvenience.
