Hmmm. I had always held the belief of 2017 being the year of NX, although I was swayed a bit by the hype of rumors to possibly being this year. But anyways, that being said, I think this is a smart move by Nintendo. They are currently in dead last place and are not taken seriously by many gamers. Sony and Microsoft will be announcing new consoles/upgrades that will release later this year (4k/VR). Nintendo probably cannot compete with that hype. They are going to pull a 2013 Sony: let the competition announce/release everything and then adjust accordingly. Heck, with it being in March, that may give them enough time to even further revise/improve the hardware after seeing Sony/Microsoft specs (if what is currently known is not factual). Also being in March lets them have all the fanfare and again, not having to compete for it.
