Sony has annunced that PS4 was at 40 million sold by the third week of May if i'm not wrong.
This mean PS4 has sold over 4.1 million the first 5 months of the year (but with one week missing, it may be over 4.2 million / under 4.3 million as well)
Using Media Create and NPD numbers, PS4 has sold 0.57 million in Japan and 1.35 million in USA those first 5 months, which mean JP+USA were under 47% of WW sales ( assuming PS4 is between 4.2m and 4.3m, let's say 4.25m; that could be a 45% of WW sales )
Huum, back by end of 2015, the JP+US sales were about 41%, this mean that actually the JP+USA marketshare is increased a bit.
Well assuming USA+JP was still about 45% in June, PS4 may be at almost 41 million by end of June.
Not sure about shipments...
