@Kyros: I didn't say all the cores would be distributing work, you could perfectly assign that to a single core (or a single thread which may not even occupy a core the whole time).
The transistor number problem applies, but that's outside the scope of my post. I started with the assumption (an assumption I'm not sure about) that the PS4 will use an architecture similar to the Cell. If I'm right, what will happen if that's the case is that the number of transistors they're able to use will be enough for more than 1 PPE and a few SPEs.
Remember that for the PS4, they will want to not only make PS3 developers happy but also make it as easy as possible for new developers to use their machine efficiently. If their architecture is neat enough, they can achieve both of those goals without even using a Cell-like architecture. I think they must have learned something from the PS2 and PS3 (both are hard architectures, but the PS2 didn't suffer much due to it since it was successful enough to force all developers to work as well as possible with it).
