It's just not practical. We get digital sale numbers only when a company wants to share that figure. So VGC is not tracking the digital sales, they're just adding that number to the total.
And let's say they add that number just to let others know how it has been selling digitally: Ex. Mario Kart 8 is at 3 million retail in 1 month, and Nintendo announces it sold 100k first week digitally (just an example). We would have a total of +3.1 million, even though it has probably sold way more digitally. It's not accurate Weird saying that on this site.
At least that's my opinion.
Bet with bluedawgs: I say Switch will outsell PS4 in 2018, he says PS4 will outsell Switch. He's now permabanned, but the bet will remain in my sig.
