It's becoming a bit of problem right now and is going to most likely increase in the future, as it means the numbers are never going to be fully representative of a game's true overall sales. Official numbers of Pokémon Sun and Moon hit 14.69 million by the end of December while VGChartz physical only numbers are at 13.24m by March 11th, so it's quite a big difference, showing the need for one day adding in digital sales too.
