How dare you!!Especially with how exclusives on the PS4 and Switch are selling better than ever. I don't see why not.
Yeah, it's great how open Nintendo is with that kind of information, then again they are primarily a game company, so it makes sense that they'd go more in depth than the other two with their reportings.
Still it's annoying with Sony that they are so tightlipped and don't even get me started on MS.
I think the only sales number we know from Microsoft is Forza Horizon 3 was over 2.5 Million and Halo 5 Over 5 Million. Then again they haven't released much this gen so that's probably another reason..
