The PS4 could be an AMP design if you consider the (closely coupled) GPU a processor.
It doesn't require the same gymnastics as the PS3 though because both the main processor and GPU are more capable. The SPUs were required to perform computation that the anemic PPU could not do as well as fill in where the pre-unified shader model GPU was unable to keep the pace.
Memory was shared on the PS3 but, from the SPUs, required explicit put and fetch operations.
