I'm suggesting that not ALL leasons learned will carry from one to the other because of the specific process... PS4 and X1 use the same architeture and still PS4 is cheaper to produce because it have a bigger bulk and got more cost cut due to it and leasons learned because of it, while X1 got some of the leasons learned from PS4 it didn't get all because both chips have differences.

How are you saying about the same process and architeture while assuming PS4Neo gets the bigger node and Scorpio get the smaller node, because of reasons?

I never said that Scorpio get's a smaller node than Neo. - Perhaps you are getting the terminology confused?

And you are right. Most non-fab related lessons/improvements will not carry over between the two, but that's also not the argument we are having.

Also the Xbox One chip as far as I know is larger than the PS4's, so it's more expensive to manufacture on size alone.
However... Not sure if the eSRAM can get away with cheaper patterning though as it's an inherintely simpler and predictable structure just like NAND.

So if both are on the same node, how will it get cheaper and faster transistors for it to be smaller, needing less space and CUs?

My arguments is that since both cards aren't exactly equal not all leasons will be transferred, can be 70 or 90% but not 100% because some improvements will be dependent or on the different aspects of the cards and if Sony order 3x more units than MS then they will get more bulky reductions .

Yes I agree Xbone is more expensive because of Size and eSRAM help on that cost (not only because it makes the chip bigger, but also is another part added).

But Sony chip isn't smaller due to having less but more powerfull CUs, and probably because having better transitors to reduce the size of the card would mean bigger and not smaller costs.
