You can't agree with what? That adding V-bucks for Fortnite (and whatever the in-game currency for Rocket League is called) to the Series S is going to be more appealing to at least some people than a Seres S without those things?
Amounts of in-game currency provided through perks are generally very small, especially when tied to free services.
I can't agree that it should be looked as the first bundle that adds value without increasing price, because well as you said yourself it is a free game not everyone play and there also other ways that gives that currency for free. And as I also said, but if customer bases sees as added value and buy because of it no problem.
