PS4 is going to be compared badly from last year numbers, because January 2018 was very good for PS4 worldwide (thanks for JP and MH World). I prefer to see what PS4 is going to do in Feb and March compared to last year to make a better guess on PS4's performance for 2019.
As for Switch, little by little aproaching the same baseline of sales as last year. I really think sales are going to be flat this 1st half of the year compared to 2018. JP maybe is going to be better but i won't be surprised if EU and US are lower than last year.
And XBO showing better than probably is doing in reality, because i don't really expect XBO doing so close as last year without the holiday deals and without a recent XBO X console like last year.
These very first months of the year are going to be really hard to track correctly i am afraid. Until NPD's and Q4 results won't know for sure.
