ok u guys,
i looked at some prices. apparently the cost of ps3 cell chip was around $175-$230 when it launched. the RSX gpu in the ps3 was based on the nvidia 7800 gpu, a high end card, which at the time retailed for $600 when it came out. add bluray which was more expensive in 2006 to make and somehow, sony sold the ps3 when it debuted at $600.
so, high end internals and fortunately, the ps3 was also quite high-end externally. the slot-loading drive, for example, is the softest spitter and eater of discs i have ever come across. in comparison, the new slim ps3 has a lower-quality slot-loading drive, in my opinion. not to mention the extra emotion engine chip that gave the ps3, full compatibility with ps2 games.
all for $600.
i can't see why sony can make a cheaper ps4 today (maybe $400-$500) using nvidia's latest and greatest gpu line which is the 6xx series (i like nvidia ok), and an updated cell processor with 2 ppe's (total of 16 spe's), 1 GB of XDRAM, 1 GB of VRAM, bluray, wifi, bluetooth, etc?....
and an updated exterior shell and moderately similar slot-loading drive found on the slim ps3?
sony doesn't even have to redesign the ps3 controller. just keep it as it is to save on r&d cost. maybe make it white, so it matches my walls.
