Using Ryng Tolu's estimates for Jan/Feb, here are the YTD numbers rounded to the nearest 5k.
PS4, ~620k (up from ~610k)
NSW, ~550k
XBO, ~545k (up from ~370k)
All 3 are doing great. PS4 is pretty stable, X model and promotions are giving XBO a strong increase and Switch had a solid first Jan/Feb.
Looks like its going to be a very good year for the console industry.
