Whats the margin of error on Vgchartz hardware? + or - 10%? Anything which falls within that range is probably just noise. It would be like saying that the poll results were up 2% on a poll with a 3% margin of error. Statistically noone ought to pay any attention to it, its just noise on the graph.
Smooth out the sales of the PS3 to 2 week periods to remove noise and put a pointer saying this is where Uncharted 2 entered the market and you'd probably see nothing of significance.
If we keep changing the meaning of system seller to ever lower quantities of hardware it really dilutes the meaning of the words. So in the future do we go:
Uncharted 2 is a system seller.
Metal Gear Solid is a system seller.
Halo 3 is a system seller.
Wii Fit is a system seller.
Wii Sports is a system seller.
and just keep increasing the size of the text. maybe next year we can say:
God of War is a system seller.
