Well, PS4 is released in China by a week, and Sony still don't have annunced some number's? I remember that Microsoft have annunced the XBO shipment in china in the same period... when do you think that Sony will annunced the official number's for PS4 and why nope, for Vita?
EDIT: seem that PS4 is at 73,000 as for now (21,000 Vita)... but is not 100% confirmed.
