Yeah, no. At least that PS4 figure is wrong, no idea about XBO.
The official global figure for January 1st 2018 is 73.6m and We know from NPD and Mediacreate that Japan+USA = 1.69m for Q1, which would leave just 1.31m for EU+RoW+Rest of NA.
Lifetime the ratio's for these two sets of countries were as follows: (as of January 7th 2018)
USA + Japan = 39.14% of sales
EU+RoW+Rest of NA = 60.86% of sales
IHS figures, with NPD and Mediacreate would put Q1 ratios as:
USA + Japan = 56.3% of sales
EU+RoW+Rest of NA = 43.7% of sales
That is far too big of a change. So I believe the PS4 figure from IHS is definitely wrong.
