Scarily on week 5 of the aligned launches of PS3 Slim and 360s for US is the following.
PS3 Slim 5th week in America moves into October, which is naturally a better selling time of the year. You would expect any console to do better in October than in July.
360's 5th week = 103,000 July.
PS3 Slim 5th week = 84,000 October.
360 is just unstoppable in US. If M$ had of waited and had more units available in September/October we may well have seen 180 - 220 k a week on it's 5th week.
