6 times is not a lot. 720p30 to 1080p60 requires 4.5 times as many pixels to render. Add 3D and you need 9 times the current power. Most games don't even make 720p30 atm. If true, I guess 1080p60 tv's will still be under utilized next gen, never mind 3D at 1080p60.
If you apply Moore's law while looking at a 2013 release date we should get 16 times the power of current gen.
Let's hope they at least stick a decent amount of ram in there this time and an ssd drive for caching.
