Nintendo Direct is ignoring April Fools and scheduling a presentation for April 1st. According to their latest Twitter:
Catch a #NintendoDirectNA about #WiiU & #3DS games on 4/1 at 3 p.m. PT. Don’t let the date fool you: This is no joke! pic.twitter.com/alsJ5Ty5b0These always provide a nice glimpse at things to come. Possibly some Spatoon? New 3DS titles? News on the Zelda date push? Hopefully no jokes included as it airs tomorrow.
