I haven't followed all of this, but I wouldn't bat an eye at 9 tflops. I don't think that's the case, but I'd be fine with it. The idea they're going with a jaguar CPU is impossible to take seriously though.
9 tflops would probably help them more than 12 or 14 anyway. They'd still have a huge graphics leap over last gen, and they'd be significantly cheaper. You know, the ACTUAL thing that matters. The start of last Gen has just melted people's brains.
PS4 didn't blow up the Xbox One because it was more powerful. It did it because it was powerful and 100 dollars less. And, basically, it wasn't another PS3 (launching a year later at TWO HUNDRED dollars more). Short of Sony being that dumb again, MS was always doomed worldwide. But it really was the cost difference that made the biggest impact. Like it has since basically forever.
