Not familiar with the site (run by an ex-Destructoid), but according to them, one of their two sources on the matter is the same that leaked Until Dawn: Rush of Blood ahead of its announcement.

In the past few days, Let’s Play Video Games has learned that not only was the Eurogamer report accurate, but the detachable NX controllers will support basic motion control, similar in fidelity to the Wii Remote Plus, and a form of “advanced vibration force feedback”.
LPVG has learned that these controllers are designed to phase out the Wii Remote over time, featuring much of their same functionality. Players with existing Wii Remotes will be able to use them for some multi player titles, but not all releases.
The force feedback functionality of the controller has been described by one source as “very similar to the Vive controller, in that it alters intensity, pulsing patterns and duration of vibration to mimic the sensation of a range of different movement types. It’s not just one vibration for all situations, there’s a notable difference between the hard abrupt feedback of a sword clash or the softer, longer thud of something like hitting a tennis ball.”
One of the titles which will support both the new NX detachable motion controllers and Wii Remotes for multiplayer is Just Dance 2017.
