Here is part of the interview:
HiHD: What are the primary erroneous points of information/misconceptions out there in blogger-land about PS3 in general and vs Xbox?
HIRAI: I have heard many people say our competitors' systems are just as powerful as PS3. That simply is not true. No other next-generation entertainment system pushes the envelope on advanced technology like PS3. I have heard people say that a high-capacity game delivery vehicle like Blu-ray isn't necessary in a next-generation computer entertainment system. You just can't expect that the 9 GBs of storage capacity found on today's DVDs are going to have enough space to hold tomorrow's games. Developers have already pushed the DVD to its limits in terms of space used. We had games like 'Resistance: Fall of Man' coming in 16 GBs at launch. That game simply wouldn't be possible on any other system without using multiple discs. There is no doubt in my mind that you need more capacity on discs for truly next-generation gaming, and Blu-ray gives us that space.
