Kaz Hirai has declared that PS3 is the undisputed heavyweight in the three-way struggle between gaming consoles, and despite what Sony's rivals might claim.

Speaking to Blu-ray the Sony president said, "I have heard many people say our competitors' systems are just as powerful as the PS3. That simply is not true".

"No other next generation entertainment system pushes the envelope on advanced technology like PS3."

He did admit, however, that in pushing the technological envelope several difficulties arose for Sony, all leading to the well-publicised stock shortages and launch delays.

"We were asking our teams to develop millions of components for the PlayStation 3, like the Blu-ray disc player and cell broadband engine, that had previously only been produced in the thousands", Hirai said.

He went on to say that the inclusion of Blu-ray was essencial for data storage reasons, "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 9GB of storage capacity found on today's DVDs are going to have enough space to hold tomorrow's games".

It was a matter of the Blu-ray or multiple discs he concluded, and I think we all know what we’d prefer.
