What are these weekly sales based on ioi? A couple retail sources or projections based on last month NPD?

 

I'm assuming the the former. However, weren't the vgchartz weekly sales pretty unreliable last month? Didn't Vgchartz have 360 at 337k last month before NPD and then NPD was only 199k?

I believe its the former, but as with any small sample you use to project data, any skewing in your sample will end up being magnified, so if their retailers sold extra 360's you could see how their projections would be skewed

 Right and I hope they can refine their algorithms to be more accurate so these weeklynumbers begin to mean something. We will see.
