Bear in mind that all retail LE Halo 5 sales and Halo 5 bundles are counted as 'Digital', so apples/apples comparisons to your typical "20%" titles are impossible.
That said, if we get some good leaks on H5 bundle sales and LE edition sales from the NPD guys, we might be able to approximate things.
By my own estimates I think the actual DD number of people not getting the game from a store in an LE package or Halo 5 X1 bundle would be more like 25% or less.
Actually that halo 5 LE was included in the 930k NPD last month. SO that 300k is all raw sales.
