Remember that Xbox 360's were not readily available until March/April, while PS3's have been available since the last week of december. Sony did a much better job of producing them to prevent any supply constraints and sold a few more units then the 360 which just couldn't keep up with production. In other words, Sony overestimated demand and had more units available for sale then the 360. Since they were able to keep PS3's in stock at many of the stores, they sold more. Micro$oft, on the other hand, underproduced the units and it cost them some sales. One thing that I notice when you run the PS3 vs 360 sales chart is the huge spike in 360 sales the week following the PS3 release. It looks as if a large number of people were waiting for the PS3, but once it came out, they bought either a Wii or a 360. I think that Sony had a great launch. I was very afraid that the PS3 was going to see another delay, but they got production started and were able to keep up with demand. Since demand didn't exceed supply, everyone who wanted a PS3 got one. That is a good launch. Of course, Sony would have loved it if demand exceeded the supply, and they could have been the hottest toy of the season and gotten a great deal of publicity. But Wii all know what happened!!!
