'Opus' and 'Valhalla' are the supposed code names.
"Opus" will be the 3rd generation chipset that will fit in any previous 360 console. Even if it has an undependable Xenon chipset. MS is making these to replace older units that have red-ringed. And according to the article, still no HDMI.
The "Valhalla" chipset will be both 65nm CPU and GPU on one single chip. Which usually means only one thing - the 360's getting a redesign...
