During an investor call in Japan late last night, Sony confirmed they are working on a "future platform." Although few hard details were revealed about the platofrm, this is the first official mention from Sony of these plans.
When discussing an increase in research and development costs over the last quarter, Sony’s VP and CFO Masaru Kato said:
"For the home equipment the PS3 still has a product life, but this is a platform business, so for the future platform – when we’ll be introducing what product I cannot discuss that – but our development work is already under way, so the costs are incurred there.”
Kato said whatever Sony is working on will have a different kind of launch than the PS3. The losses they have suffered on the PlayStation 3 had to do with the price of semiconductors versus retail prices. Sony has since created its own semiconductor facilities, and this mean it is "no longer thinkable to have a huge initial financial investment like that of the PS3," according to Kato.
