Far as I know they still hang around 10% of floppy sales, though given the chaos on the digital end with comixology and such, that figure might have dropped for all I know.
Not a inconsiderable figure, if it's still around 10%, but certainly nothing to get excited about.
But we know we can't take sales rankings very seriously. IVC2 is roughly the best we have, and there's plenty of problems with them, their sample population, and the way they organize data.
