Or, MS could abandon SDRAM and make XB2 close to PS4 memory model (just better with HBM).
The issue here is doing so breaks the platform with XBone, while Sony will be doubling down on platform growth.
In the longer term, MS would be attracted to ditching the SDRAM, but shorter term interests could prevent it.
But if they are planning not only Scorpio but generations after that, they might prefer better memory architecture switch now.
Even with the SDRAM I am sure the extra year's worth of tech progression will allow performance bonus vs. PS4.5.
Issue is whether it will be enough to make a difference, meanwhile PS4+4.5 will be reaping benefits in exclusives sharing some optimization.

That bolded part...... this is the K kinda stuff that makes me wonder how some here really think these things work.

let's look at the 1080 card from nvidia. This is a 9TF GPU that cost $500 with a power draw of over 250W. Just a GPU.

It is impossible, by nvidia, Intel, and or anyone else to make an APU that has a GPU with 6TF of power on the same chip that there also exists an 8core CPU. And have that chip draw less than 250W. Even if by some miracle of  16nm finfet fabrication that were even possible, it will be impossible to have that all be in a box that costs less than $800.

The amount of power MS will have to go for to allow for a memory architecture switch now to allow them adequately emulate all existing XB1  games to ensure full BC with the existing XB library is just too much and too expensive even if they waited till 2018. So as long as they are using SDram for now, that limits how powerful their console can be. Will it be more powerful than the XB1? yes. but it's just not possible to make it more powerful than a PS4k, 

I just don't see how they can do it. Even if they want to split the cpu and GPU. the sdram still has to be there to ensure BC, but all that just means a much more expensive box. 

Ah well, we will see I guess. This post is not directed at you, I just took the bolded part and used it to elaborate on something else i was thinking of. I can tell you also get where I'm coming from with all this.
