Exactly. He can claim that 50% more cores doesn't net you 50% more power, but he is ignoring the fact that the PS4 also has 50% more ROP's/TMU's/etc. A matter of fact, the 7970 has double the cores of the 7850 and gues what? It performs twice as well!
Then add in the fact that the PS4 has WAY more bandwidth and hUMA, and it is easy to see how it will perform twice as well like some developers have directly suggested. Get your heads out of the cloud people...

It almost has 50%+ of everything, except for a few things like the Geometry Engines, which is going to be a big part for next generation, everything will have depth, hopefully no more flat blurry ground.
The bandwidth advantage of the PS4 isn't as big as you think either, the Xbox One has lower bandwidth requirements to begin with due to the slower GPU, the eSRAM will give it that little extra boost.
Of course ideally, Microsoft should have went with GDDR5, but probably due to immediate costs (And possibly CPU performance due to the roughly 20% added latency?), decided against it, GDDR5 doesn't enjoy the scale of economies like DDR3 does and it also requires a more complex memory controller, which costs transisters, the transister budget that could have been spent on the memory controller and GPU was pretty much all thrown at the eSRAM and then some.
On the flip side, once low-end GPU's and IGP's start using GDDR5, then it's going to be good news for Sony, it's going to get cheaper, high-end cards don't really sell much in terms of volume, so their shift to GDDR6 won't impact prices much.
Where-as DDR3 is going to be getting more costly from here-on-out, DDR3 prices have already increased over the past year, that cost should jump for Microsoft as the PC shifts it's focus to DDR4 production.
