I say yes, without a doubt. PS3 sales are still incredibly strong, remember, it sold 300k units for NPD in June, despite a price cut from from the competition. I doubt it will beat out the 360 in sales for Q3/Q4, because I expect this to be the 360's best year and the PS3's second best year, but it's going to win a handful of weeks.
In the end though, the gap will increase in the 360's favor. The PS3 won't be playing catch up anymore until the magical $200 price cut.
