Sony had a marginally higher shipment rate because Microsoft stuffed the supply chain in late 2006 and didn't have to refill shipments till a third of the way through the year in any major way.
Apart from Sony selling 1 and a half million more PS3s than Microsoft sold 360s last year, Sony also sold 1 million more units for the first quarter of 2008 (excellent for a relatively slow period of the year), maybe Microsoft stuffed the chain during holiday season 2007 as well.
