It was an announcement that drew a rapturous response from the assembled journalists and other attendees.
Now it looks like Sony are back tracking from that statement, with various post show interviews clarifying the meaning of the statement. Sony won't be blocking second hand sales of its own PS4 titles, however third party developers are free to do as they choose.
So exactly the same as Microsoft's commitment on the Xbox One then.
With Sony also announcing that online play for PS4 owners won't be free any more any perceived win for the PS4 has now been comprehensively wiped out.
