I can play that game too, call me when the 9 million phones actually ship and are sold.

Apple's 4.5 million figure was prepaid preorders from my remembrance of the news articles, the 9 million from Samsung is product in channel. Any salesman will tell you thats a big difference.
It means Samsung have had store orders and customer orders for a total of 9 million it does not mean that they have sold (and been paid) for that many units, as the 9 million covers phones unsold sat on shelves in phone stores.
Not saying the S3 will not break the iPhones sales records in time (it looks a decent phone if a little big for my tastes) but press releases using statistics can be bent to mean anything so are usually useless. That includes Apple, everyone has an angle so you have to look at the details to see how the claims line up against each other. Barking statistics without the analysis is pointless.
