On other hand, Switch had launch in March 2017. and launch always gave huge sales in any case, and January and February of this year shouldnt be strong in any case. So March of last year should easily be stronger than this years January and February.

 

PS4 in US and Japan is down YoY.

On other hand it wasn't severely supply constrained this year. 

Who and when was supply constrained?
