According to VGchartz (don't complain, the original article uses only 5 retail chains itself) gives close to the same story (Weeks of July 7, 14, 21)
PS3 - 22102 51763 45101
So it had an increase of 134%, then a drop of 13%. Of course, focusing on percentages gives them a great result because their overall numbers were (and are) still quite low. 2 weeks after the price drop, they're selling 23000 more units (I'd expect that number to drop further), which isn't insignificant. During this same time, 360 sales have dropped 2000 units per week. However, Wii sales have increased 7000 units each week. While a $100 price drop on the PS3 has caused them to move over 52000 additional units, the Wii moved 22000 more units just by increasing production. As more factories switch to Wii production, I expect that number to continue to steadily rise.
The price cut is definitely working for Sony. The problem is that it can only possibly work for a limited time. Estimates put the number of unsold shipped PS3s at about 2 million. What happens to PS3 sales once the 60gb systems are sold at the lower price? Perhaps Sony is hoping to cut the price on the new 80gb SKU just after the holidays.
Overall, the surge in PS3 sales is bad news for the 360, but completely irrelevent to the Wii. There are a ton of great games coming out for all three systems as the holiday season kicks off in August...it'll be interesting to see what happens to those numbers!
