Why does Nintendo share more sales figures than PS4 and X-Box 1 and third parties?

Makes you wonder why Nintendo always shows the info, even during the Wii U era.

I don't think Nintendo were public about their console sales for WiiU?
Other than saying how many units they expected to ship certain years. (And those numbers could change drastically later on in the year.)

Say what? Nintendo disclosed Wii U's lifetime shipments at the end of every single quarter, just like they have for every other console of theirs since 2001.
