(1,5M copies x ~30$ = 45M $ compare this to 2M $ from Kickstarter).
Errr, it is not that simple so no. But we get the idea.
Retail price for D:OS is 45$. I take 2/3 of it, I think that is good estimate, but let's say they only have 20$ from one copy, it gives us 1,5M x 20$ = 30M $ - still lots of money.
You can't compare D:OS2 with Skyrim.
If I would expect that D:OS2 sell as well as Skyrim then I would expect not localization but full voice acting.
