Let's break that down a little bit. Because this was a conference call to announce quarterly performance, we're assuming that these downloads were performed by the 1.5 million people who managed to score an Xbox 360 during the period.

This means that 750,000 people downloaded 4 million items, or a download rate of 5.33 Xbox Live Marketplace items per connected gamer.
