It is still unknown if this is 100% true, because The Inquirer does not provide any references.
Their claim is that the Blu-ray drive in the PS3 will cost upwards of $100 for each unit at launch. Assuming this is correct, it’s quite a steep price for a single PS3 component. With this they also still have to stick in 512MB of high-speed RAM and the much talked about Cell processor, and thousands of other components to make everything work together. In the end, the launch price could be a little higher than originally expected, as I doubt they will take a loss on each unit to get their release numbers up.
