Here is the problem with 8gb of GDDR5 ram. From my understanding GDDR5 ram is not available in large amounts so this could cause a shortage for the PS4. That much ram will add a considerable cost to the console. If the PS4 cost double than its competition then it could be the PS3 vs the 360 all over again. Also the size of the memory chips is pretty small which means they will take up a lot of room on the motherboard. This could be a very big risk for Sony but if the system sells will probably be the deciding advantage.

Cell is not the only thing that make ps3 expensive the blu ray also contribute to this when ps3 launched less expensive blu ray was about 200 dollars.
