You're killing me.
1) The WiiU IS ~2x that of the PS360. Its CPU is slower per core but a more efficient and better CPU. Its not that much worse, if at all. The RAM is slower but many times more in quantity PLUS the very fast 32MB of edram that helps out in many different ways. PS360s GPUs are about 250GFLOPs while nearly everyone (especially after the 500MHz rumor) say its about 500GFLOPS... PLUS it is a far newer and more modern GPGPU and simply does a ton more over PS360s in terms of raw power, functionality, and various technologies. Anyone would say its safe to say WiiU is 2X the PS360 who knows about the tech.
2) Reread the rumors or just go to my thread with them all. It clearly says the PSOmni is about 2X the WiiU and then later says the neXtBox is about 2X the PSOmni. "Microsoft is the most vague out of all of them. It’s slated to be the most powerful out of all the next gen consoles about 4 to 6 times more powerful than Wii U and 2 to 3 times more powerful than Playstation Omni."
If the Wii U was twice as powerfull then all the games would easily run in native 1080p, but they don't they run in 720p. Halo 4 runs in native 720p and looks crazy good doing it. Lots of games on Xbox 360 and Ps3 run in native 720p. Where are the 1080p Wii U games?
The Wii U has more modern parts than the PS360, but Nintendo picked those parts because they were inexpensive and effiecent. The Wii U is only marginaly more powerfull than the PS360, not twice.
"That's a lot of numbers, but it's safe to say that more and more evidence is placing Wii U alongside Xbox 360 and PS3 versus a drastic leap over the current generation. Developers are definitely coming to terms with what Nintendo's new system will be capable of, but it's also clear that Nintendo's divergent approach has once again focused on finding innovation in control and software versus attempting to compete in terms of raw power."
