Neither of which is likely due to the PS3's architecture, namely the Cell. The Cell processor's die will shrink no further and nobody has bothered to try in many years. Nobody is going to invest the time or effort to make a slim PS3. Why would Sony bother to spend hundreds of millions of dollars to chase a handful of sales when the PS4 is such a huge success? Why would they divert resources from a far more successful, more profitable product? Even if it does happen what type of impact could you possibly expect it to have? The PS3 launched a decade ago and Sony has no reason to struggle to maintain its already low sales. With only a couple million sales for the entire year I doubt they will see any viable reason to produce a new model. I can not even see any reason for a price cut unless it is to clear remaining stock. What I'm trying to say is that the market has moved on and there is no indication that Sony will go against historical precedent or consumer demand and work to increase sales for a console that is effectively dead. Production will likely cease within the next year and no amount of wishful thinking will make your pipedream of the PS3 remaining on the market until 2020 even a remote possibility. They are not going to fight for a few hundred thousand sales a year for four to five years, that is simply not going to happen.
