When an investor asked Sony to explain why there had been an increase in research and development costs, a Sony senior executive said that work on the PlayStation 4 is “already under way”.
“For the home equipment the PS3 still has a product life,” said Masaru Kato, the Sony chief financial officer, according to Eurogamer, “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.”
Whilst this is exciting news for PS4 fans, it is not inconsistent with past remarks, and is in-keeping with Sony’s stated 10-year lifespan for the PlayStation 3. The PS2 hit its 10 year anniversary last year; the PS3 was released four years before that, so this may suggest a two year wait until a 2013 launch.
