The PS2 has Emotion Engine and Graphics Synthesizer, the PS3 has "teh Cell" and RSX, they are extremely different and not compatible unless it's via hardcore software emulation (they started it but it's still far from perfect)
If the PS4 has an upgraded Cell, Cell 2 or anything that is compatible with the PS3 Cell, PS3 BC should be a no-brainer...
