Am I one of the few that has always been willing to pay for a very high end model in a standard size separates case? I just simply don't understand why they have never done it, unless I really am of a small select bunch. Something along the lines of the original specifications, most of the ports on the back (2 HDMI, 2 Gbit, 6 USB, etc) and card slots on the front with 2 USB for charging, small display on the front with buttons, a PlayTV type of unit at the back (the full SCC onboard) with standard RF and Satellite/Cable coax inputs and a CAM slot (they could also do deals with certain operators/broadcasters to do this in software, linked to your PSN account), normal IR receiver, even a Blu-ray burner drive with a tray.
I'd pay 600-800 quid for that depending upon exact specifications.
