There's no way Sony is going to allow that kind of discrepancy in power. Just 2 tflops, even if with those tflops you can do more than in Polaris, above Xbox One X would be PR suicide. Especially when the competition is doubling that number. No, I'm pretty sure the two top tier consoles are only going to be 1-1.5 tflops away from each other.
But that's the only way to keep the 500$ budget from overflowing. Why do you think the one X didn't have a permanent pricecut yet? Simply because it's too expensive to produce otherwise. Anybody who's expecting over 10TFlops should also be ready to shell out over 500$, as the hardware will become too expensive otherwise
