That if you only want to compare retail numbers you're are probably going to be right.
But like i said before, leaving behind digital sales benefits a lot more a game like Pokemon than a game like GOW. GOW with digital sales should be at least around 7'5M if not more. Pokemon Let's Go digital sales should be a lot less in comparison, so probably it will end around 10% more that what you expect at retail, so let's say around 7M.
Oh I see, yea my bad then idk much still about digital+retail... But are for example all those switch with pkmn bundles count as digital? And I guess in the nintendo website figures they include digital sales right? Because I found pretty big different between sun and moon at retail 14M and figures there 16M... Thanks :)
