If you feel you can stomach more sales "percentages" in lieu of sales "figures", then Sony's boast today of a 300% increase in PS3 sales is something you could maybe look into.
"Our top retailers have reported a 300% lift in PS3 hardware sales and an increase of 140% in total hardware revenue across the PlayStation portfolio when comparing the first week of September to the week before the $299 price adjustment", says a press release sent out by Sony earlier today, so breathless with excitement they couldn't squeeze a single comma in there.
What that means is that the PS3 Slim is selling, and selling well. How well it remains to be seen, as we won't get good, real numbers until this time next month, but even going by the PS3's poor performance in July, a 300% increase means pretty damn well.
