I think Sony may see this as an opportunity to use a clearly more powerful chip that can be sold at higher margins but costs the same or even less than the current PS4 APU to produce (especially when yields improve and the cost of using the new finfet process comes down)

Yeah, this would be more profitable then the usual  slim SKU which often arrives with a pricecut (negating much of profit margin gain from the cheaper production).
