During an earnings conference call, Sony CFO Masaru Kato said his company is not planning a major loss to be incurred with the launch of PS4. Emphasis on "not planning." "Unlike PS3, we are not planning a major loss to be incurred with the launch of PS4," said Sony CFO Masaru Kato during an earnings call that ended moments ago. "At the time we developed PS3, we made a lot of in-house investments to develop the chip, the Cell chip. Development of the chip saw the silicon processing and all the facilities invested by us ourselves. But this time, yes we have a team working on chip development, but we already have existing technology to incorporate and also product investment and all the facilities will now be invested by our partners, other foundries, so we don't have to make all the investment in-house."
