Seems they are upgrading old systems with the 65nm CPU right? I'm pretty sure that my 360 is 90nm CPU so I'm hoping the system lasts atleast until they have the 65nm CPU & 65nm GPU out.
In my opinion they didn't develop a new board, they just mixed and matched parts and put them on Xenon (version 1) motherboards. But as others have said, hopefully they have fixed most of the bugs with this revision!
Actually this OPUS board has the HANA chip just like falcon. That means you could solder an HDMI port and make it work ^^
