Posts by DCUO Creative Director Jens Andersen about the PS4:
 * Our intention is to have PS3 and PS4 players playing on the SAME server.
 * Also, the graphics are on the client, not the server, so we intended to make many enhancements to the graphics on the PS4 client that you would not see on the PC.
