I would say the shipment of PS4 will be approximate 4.3~4.4 millions, so the shipment of PS3 would be about 3.4~3.5 millions in Oct.~Dec.
Therefore, there is still a chance that in the sell-in numbers, Xbox360 still has slight lead than PS3 by the end of 2013.
If this is the case, then it is a great milestone for Microsoft and Xbox360 and if in spinning talk, Microsoft delivered their promise that Xbox360 will sell more than PS3 in last generation (sell-in number).
