If I remember correctly even Trevs source said the system is "planned" to launch this year. Not confirmed..
I'm not quite sure what the difference is there lol.
This is his exact quote: "My verified source from Nintendo has informed and shown proof of an internal US marketing budget and scheduling overview for 2016 focusing on Wii U and 3DS, with key parts highlighting The Legend of Zelda NX to be a holiday 2016 release either same day at Zelda Wii U or shortly after during the Nintendo NX holiday 2016 launch window."
Sad we can't look over the videos anymore.
