The Sony PS3 is a total sell-out along with lots of chaos at the stores on launch day. An AmTech analyst (viai Kotaku) estimates that Sony only shipped about 125,000-175,000 Sony PS3 consoles in the US yet. The word was after the shipment cut that 400,000 PS3 would be available in the US at launch.

There are no confirmations yet on the actual numbers of shipped Sony PS3 consoles. Sony said though in a report on Gamesindustry.biz to still plan to ship 1 million Sony PS3 by the end of the year. This number refers to global shipments of the PS3. But in any case there is still hope to find one retail before the holidays.
Apparently the top selling Sony PS3 games are Resistance: Fall of Man and Madden '07. More Sony PS3 news.
