I want to know the answer to the following question:
What was the software attach rate in the US for the 360 by March of 2008?
All the background I'm provided with is that "By March 2008, the Xbox 360 had reached a software attach rate of 7.5 games per console in the US; the rate was 7.0 in Europe, while its competitors were 3.8 (PS3) and 3.5 (Wii), according to Microsoft.". Is that enough to answer the question?
