Sony is stuck because they don't want this generation to end. You make a 6 TFLOP PS4 and the gap between the machines will get too large for parity. 

MS has no real vested interest in seeing this generation drag on forever so their philosophy is different, they want more of a full next-gen machine rather than just a stop gap. 

sorry, but i think you're confusing cores with compute units (CUs). currently the APU inside the ps4 has 18 CUs (again, compute units) active, while the Xbox 1 has 12 CUs. The die shrink to 14nm basically allows the APU to have anything between 36/40 CUs, which will probably be the case for both new APUs. Also, it has been pretty much confirmed by now that all games coming out from October on must have a Neo mode available as well as a vanilla mode for the original system.

So unless you have specific sources to contradict all the pretty much confirmed parts of the rumor, you should realize that this 30% number you came up with is just that... something you came up with, having no basis in reality.

It's not part of the discussion what Sony needs or needs not do. It doesn't matter what amount of money MS has or doesn't have. Those are separate discussions.

This is what i find most puzzling. ... For me, and i said this before, i don't even see the PS4k coming this year.
They alrewdy have PSVr to oush this year, something as big as a semi new console will at yhe veey least need its own year. 

I look at all these rumors rhe same way i looked at those of orbis/durango. They were all kinda in teh same ball park all kinda true and also kinda wrong. There is just not a chance in hell sony would let MS make an upgrade that is almost twice as powerful as their own upgrade when they are all using the same vendor and especially if all it takes is waiting a year. Is there any reason anyone thinks sony won't or can't wait a year? What exactly does sony have to gain by coming a year early? 

Too large for parity? You are beginning to sound less reasonable and more wishful.

But since you seem to know so much aboit MS. Helpe understnd something. What is the UWP about? And why has "parity" not stopped MS from releasing XB1 games for PCs?

And you really think that MS is fixing on making a console that will start having exclusives that u domt see on the XB1? Even tho Spencer was the very first one to ever mention forward and backward compatibility? Eveb though MS has been pushing the UWP?

There are just rumors,  nothing officially... If ps4 néo have double new cores graphiques,  Sony have to do the same with CPU and RAM,  so ps4 néo price will be 500 or 600 $ ??? 

Polaris is fan's hope... 16-14 nm will be expensive, like Nvidia have a lots of difficults to make pascal cores... 

2016 is too early for polaris in console... 

Yes we seem to be in agreement. My problem is how eveeyone seems to be riding on these rumours. Thr onoy thing that is pretty mivh confirmed right now is that both Sony and MS are going to release new iterative consoles. And that both of them are using a 16/14nm process which is the onoy way such a thing is possoble to begin with.

Specs, release dates and evrything in between are just rumors. But yet we have people here talking like even those are written in stone.

This is what i find most puzzling. Sony has a massive advantage currenlty in this generation. They knowthat the price, the performance edge and their focus is what has got them the win so far. Of the big 3 they are the  one that is under the least amount of pressure to do anything, I mean they have so much of a hold on the console space this gen that if they remained quiet and MS announced they were releasing the XB1.5 next month, all they have to do is say the PS4k is coming 2 months later and it will stall whatever sales rhe XB1.5 could have. 

But for some reason, there are some talking here like these arent rumours and there is some sort of commitment that sony and MS has already made that they are locked to and cant do anything about. Especially when no one has even officially announced anything yet.

For me, and i said this before, i don't even see the PS4k coming this year. They alrewdy have PSVr to oush this year, something as big as a semi new console will at yhe veey least need its own year.

I mean come on, the PS4 is probably the onky console in history that took its price back up from $300 to $350 after a holiday season and YOY sales still went up by 10%. Am i missing something here?

You're aware that reducing the process to 14nm makes the processors cheaper to produce (more yeilds per wafer) right? That's why the new GTX 1080 has a starting price of around 600$ while the previous architecture was way more expensive.

Do I want them to also improve CPU? Hell yeah. Do they need to increase the RAM size? For 1080p and even VR, not needed.

Would I pay 600$ for a massive improvement? Absolutely.

Will they sell it for 600$? I doubt it.

Will it be polaris based? 100% sure

If Sony want make reely powerfull new ps4,  they have to wait HBM mémory and vegas ...  impossible in 2016... If Scorpio comes in 2017,  it could use this new technologie... 

Sony will be in a bad position,  Microsoft will say " look, i have the big one"...  In 2018/2019 Sony will arrived  in late with PS5....

At time, Sony juste need keeps hand,  and wait Microsoft show his cards... 

PSVR is exactly why they want to launch now.  PS4k has the power so they don't have to apologize for the experience.
Sure they could launch it 2 years from now, but that would define PSVR experience by PS4.0 specs, whereas simultaneous launch means
even if PS4.0 mode is available for these, everybody will point to the PS4K mode as the definitive one, the one to sell PSVR experience by.
As for the large delta in claims re: MS Xbox Dos, IMHO a good part of it comes from discrepancy in comparing just GPU to looking at total CPU+GPU.
MS will have margin with just 1 year delay to push more Hz, more CU, and they may be more aggressive in CPU/GPU arch update (e.g. replace Jaguar).
For Sony, those marginal differences by delaying 1 year aren't worth it when they want to launch PSVR now, and this is how it will be defined.
If they weren't going to launch PS4K this year, then I don't think they would want to launch PSVR now either... But they don't seem to want to wait.
