Sony has said it's waiting until next generation hardware can show a "significant leap" ahead of what's on offer today, before revealing any new hardware or software that may make up its PlayStation4 console.

The comments come via Sony Europe's CEO Andrew House, who gave trade publication MCV a big interview covering the recent new gaming stuff Sony demonstrated at E3 and talked in rather vague terms about the future.

When specifically asked for his comments on Sony's PlayStation4, House 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. That remains our philosophy. Beyond that we have nothing to say at this point."

Given that the recent Activision court document fun told us to expect Xbox 720 in 2013 and PS4 around a year later, that all seems to make sense. PS4's not built yet so there's precious little to show. [MCV via CVG]
