Sony is not prepared to demonstrate its PlayStation 4 console until the system can demonstrate 'a significant leap' in technology, the group chief executive of SCE has explained.
In a rare interview with industry publication MCV, Andrew House appeared to challenge the emerging view that the next batch of game consoles will not provide a considerable leap in technology.
Asked why Sony did not showcase the next PlayStation at E3 this year, he said: "The right time to talk about new advances in hardware is when you can demonstrate a significant leap on the current experience, and something that is going to be attractive."
"Beyond that we have nothing to say at this point," he added.
Analysts and executives at rival companies have already claimed that next-generation graphics will not leap as far forward as the current generation did from the previous.
Recently, Nintendo president Satoru Iwata questioned whether consumers will ""be able to realise the difference" between current and next generation technologies
It is widely believed that Sony will reveal PlayStation 4 at E3 next year, if not sooner.
