Phil has to hit on performance, because a) it burned him before and b) he doesn't have a supply of exclusives Sony has. I personally have different opinion on Sony's exclusive strenght, but the consensus is they rock. Therefore, Sony can have a weaker console and still win, MS can't. That's why MS is laser-focused on power and Sony doesn't have to be(but still might).
The RAM unveling thing is not relevant - of course it's awesome when you announce something everybody wants. It doesn't make you "feeling good" and important part of corporate strategy.
Now, back to cooling:
I read your post and found zero information how do they push those clocks. If they have the same chip, they have to dissipate the same amount of heat to get to same clocks. MS just presented us with the box so bulky that people laughed at it. They went all in for the thermals. I refuse the believe that Sony found some magical way of squeezing more juice. That would mean they have some revolutionary heat dissipation technology, which is unlikely. Also, that would mean a very high risk of failures, like happened with X360 and RRODs. Since RROD fiasco MS has way better track record on cooling and that makes me very skeptical around hitting frequencies on the same chip the other side cannot hit.
