this is interesting,from neogaf:
"PS4 US LTD since August 10th ~= 681k
At 34% US|WW Ratio, WW sales of PS4 between August 11th and October 4th would be ~2003k, a little over 2M
At 38% US|WW Ratio, WW sales of PS4 between August 11th and October 4th would be ~1792k
So likely the PS4 either approached or surpassed 12M sold through WW as of the beginning of October"
