So Sony, shipped 3.5m PS3 Jul-Sep 2010
Working out USA+Japan PS3 sales July-Sep 2010=1,072k
July-Sep 11=1,135k
Of course that doesn't include Europe, but it should give us some idea, as it seems unlikely one territory would deviate from the historical norm when the others dont. EG, if sales in USA and Japan are similar one year to the next, no reason to think they'd vary wildly in EU absent an outside factor.
Pretty similar end user sales might indicate similar shipments. So I dont know, 3.3-3.5m for PS3?
3.5m would put them 2.3m from 360 LTD.
Like I said, if MS wants to keep the lead from jeopardy, they probably need to cut.
Edit: corrected numbers, was off by a couple hundred k for Japan, doesn't change the gist.
