replaced units at retail under warranty don't count as a unit sold...It registers as an exchange, which is very different. the old systems are sent back to Microsoft. Also most of the RROD repairs are refurbished consoles, not new ones. If you really think so much of the 360 userbase is from repurchases then 360 has the highest attach rate in history by FAR.
