i guess more than 50% of all ps4's went to the usa
and you still ask for more?
the better supply of xbox1's is easy to explain as there is not much demand for xbox1 outside of the usa/uk therefore they can ship almost all of their new produced console to usa as there is enough supply in the rest of the world.
Sony can't just concentrate on usa as ps4 is sold the for 400 dollar=300euro while they sell in europe for 400 euro.
difference/profit 130dollar when they sell outside of the usa.
