There is no real data, only speculation. Steamspy says 2-5 M for PC only. Using NB correction by year of release you get 3.3-4.5 M for PC only.
A range of 2 to 5 M means exactly that: it could be as low as 2 M or as high as 5 M. You are choosing to go with the highest possible number within that range. And I am saying I don't buy that for even a second. I myself am not throwing out any numbers for D:OS2 sales. I'm merely saying you guys' unsubstantiated claim of 5 M is silly to me, and if I had to guess I would guess the low end of that range. Ultimately we're all guessing because none of us has the true number. You are choosing to high-ball the number; I'm choosing to low-ball it. That's it.
