80% isn't anywhere near the ballpark.
These guys tell you what the digital mix is generally on their earnings calls. Last year on consoles from AAA titles, it was around 20%. EA and Gamestop have said that mix shifts about 5% per year and this year is following that trend. So we should expect around 25% of Call of Duty was digital download, which implies if retail is down 40-50% then digital would be down 20-30% and in total, about 35-45% fewer units were sold this year than last year.
