The base PS4 has 256MB of DDR3.
The PS4 Pro does have 1GB of DDR3 though.

My less than or equal to 5% chance remains.

Yeah, on the base PS4, there's 256MB of DDR3 for video encoding (something I bet they won't need to do for next gen machines). No non conventional RAM (DDR). 

I don't think it will happen.
It is possible though.
