"A 8.5 gap would mean that the PS3 needs to outsell the Xbox360 from that point on by 500k every month to pass the Xbox360 in November 2010. This will be a really hard job for sony."
Very interesting, but its lead by 09 is likely to reach 8 million, If we don't see any price cut until september (can Sony REALLY justify a price cut right now?) the lead can grow to some 10+ units.
Not to mention how many consumers in Jan - March will be willing to spend $400 on a games console? Jan - March next year I think we will see the PS3's lowest ever weekly sales.
