It wouldnt matter. It would just come off as a nice little new addition. Kimda how the 360 didnt launch with a HDMI port and then it mysteriously started appearing in some models aroumd when the PS3 launched.
However, I feel Sony won't even bother. And rather than add a BR drive in the system, they just drop the price of the Neo.
Hell if I were them I would make an external 4K BR drive reader that plugs into the PS4pro via USB. They can easily sell something like that for $100.
