Nice updates.
RE: neXtBox OS.... 1CPU and 1 to 1.5GB RAM is expected if its a modified Win8. That simply makes sense and adds up.
RE: power usage between consoles... just because they use 4x the electricity it doesn't mean they are 4x the power of WiiU. settle down folks. AMD uses more power and runs hotter than intel or ibm. WiiU has a heavily efficient design and architecture.
Will they be more powerful than WiiU? of course. Will they be anywhere near the differences that Wii to PS360 saw? nope. Closer to 2x is more likely. But it won't be too much longer me thinks for clarification on this.
