Doubt it seeing as how the PS3 didn't*. Earlier PS3 models had Emotion on-board so unless the PS4 has it, it won't.
The problem with PS2 emulation is that it requires 2 strong CPU cores which is why were getting selected PS2 classics on PSN. (My guess)
If the PS4 doesn't have the Cell on-board, then it wont be PS3 compatible either.
