So the question many of you are no doubt asking is, are we looking at a free-flowing technical discussion or a PR exercise? Well, let's not kid ourselves - every interview that reaches publication is some form of public relations for the interviewee and that applies equally whether we're talking to Microsoft, Sony or anybody else. Perhaps the lingering disappointment for us with our Mark Cerny interview was the fact that it quickly became evident he was not going to let us into much that he hadn't already covered elsewhere. It's also fair to say that the impressive specs, well-rounded line-up and a phenomenally well-managed PR strategy have left Sony in a very favourable position, with nothing to prove - for now, at least.
