I remember it this way. I think there may have been a segment of Nintendo's website that said March that was taken down after a few hours, but the press release itself said 2017 vaguely.
I kinda expected this, though I thought it for the wrong reasons. I figured their plan was to delay it till November and dominate the holiday season. I also assumed this game was done a while ago, and they were just delaying it for a simultaneous release on the Switch. Either that isn't...
