Option #1: A new, more powerful PlayStation

The current-gen console processors are an assemblage of off-the-shelf AMD components with some level of customisation requested by Sony. In the move to 14/16nm production technology, there's a 2x increase to transistor density compared to 28nm, meaning that Sony can produce a microprocessor the same size as PS4's current Liverpool chip, but theoretically twice as powerful.

Plus they could improve and increase the GGDR5 ram. So its 2720x1520+ @30FPS max (upscalled to 4K) for games like Bloodborne and Uncharted 4, smaller games could hit true 4K resolution like the Remasters or many JRPGs.
