Following this thread multiple times a day in hope of an announcement that will let me get my ps4 out of its delivery packaging. Keep going with the good work and signs are encouraging, but any thoughts of getting xim licenced is a waste of time. I'm not at all surprised Sony haven't responded. They are not interested in anything other than controllers to play games because the ps is a console, not a pc. Its what the whole console brand and image is about. Personally I don't think they will ever change from that, but if they did it would be such a significant shift that they would probably want to do it with their own product first.
And as for breaching user agreements, of course they know about the range of adapters out there, but as has been said they're not bothered as long as there is no cheating or security breach. Evidence in the Splitfish issue.
