What Eric says is common sense: their main business and proposition are PS5 and its games.
They bet on VR too, they do cool innovative stuff there but it's a small niche emerging market, so they obviously have it as something secondary while they focus in their main business, what gives their most of their revenue and profit: their console.
It would be nonsensical to focus more on a very expensive accesory that only a small portion of players use than in their main product.
