I couldn't find the link to the NVidia graph showing predicted relation of PC retail to DD, but I used 3X as a conservative guess
Some caveats: license fee to Microsoft may be lower, since XBOX gets the (first month) exclusive DLC. I would assume that they had to make concessions to Bethesda to get that deal. But since numbers for license fees have been widely quoted at $5 to $9 per unit, I compromised on $7
