Hmm Cant seem to find it right now (duh), but I always write down when there's numbers shared from somewhere but didnt add a link :(
I did however find this: https://vgsales.fandom.com/wiki/Wii where it's stated that the Wii had sold 111k units in Italy as of August 2007 (10 months in to Wii life) and we do know that Switch was the best selling Nintendo console in Italy 10 months in to it's life which would mean that the Switch at least had sold 112k at the end of 2017 so I'm sure I didnt make 120k up from nothing. I will continue to look another day.
Oh ok i thought 120K was a confirmed number.
I remember the annunce of Switch > Wii the first 10 months, hell i posted it on Resetera myself, but it could be anything above 110K
