I'm guessing we'll something along the lines of a AMD Ryzen 7 1700 in the PS5. I'd imagine they want to stick with 8 cores for the next system. It's $320 at launch, which means in 2 years time, it should be much cheaper to throw into a $399 console. I'd also settle for a Vega 10 GPU (~12.5 Tflops), though I'm hoping for a 20 (~15 Tflops.)

Hmmm, don't know about that. Heat is a concern in consoles and the R7 1700 is a 65w TDP chipset while the Vega 10 will likely be around 200w supposedly. I can't see them going above the 150w threshold for overall power consumption (the launch PS4 uses 140w while playing demanding games by comparison). The reason MS and Sony both went with Jaguar this gen is because it only uses like 15w, which gave them both a bigger power usage budget for their GPU's. While I don't think Sony and MS will make the mistake of building systems that unbalanced again, I don't see them going over 35w for their CPU's. It's more likely that we'll see one of the lower power usage variants of Ryzen that are designed for their APU's. Such a CPU will be plenty in a console, which don't have as many background processes leaching power as desktops do.

GPU wise, I don't know if PS5 will get the full Vega 10 if it releases in 2018 or 2019. I'd guess it will use either a partially cut-down Vega 10 or Vega 11 (the more efficient and faster successor to Polaris 10), so somewhere in the neighborhood of 8-10 tflops. 

But what is the TDP of the chips in the Pro?  I couldn't find the info myself, but it has to be quite a bit higher than the launch PS4.  I do know it is rated for ~300 watts, I believe.  If they are going to keep up with PCs, to some extent, they are going to have to aim for a higher TDP.  Granted, I do expect them to use semi-custom chips, again, so they are going to be slightly weaker variants.

I'm guessing you meant 20 in your first sentence.  And, I know it's probably unlikely, since it's not guaranteed to launch in 2018.  If they can make it, the chances are greater, but I'm still leaning more towards a Vega 10.  Also, I think Sony is going to want to be around double the Scorpio to make the gap seem even larger, so ~11-12 Tflops.  If they use an underclocked Vega 10, which will also help with heat, they should achieve that. 

I seriously doubt we are going to see anything as low as 8 Tflops.  Even though not every flop is the same, it would just be mocked as barely a jump worthy of a new gen, especially with reasonably priced 15+ Tflops cards launching by then.  It would also only be ~4x more powerful than the OG PS4 and less than twice that of the Pro.  At least with ~12 Tflops, you're looking at ~6-6.5x the OG PS4 and ~3x that of the Pro.  I think the vast majority of console gamers would be fine with that.  If they only went with 8/9 Tflops, it would probably also give MS an easy way to win by just taking a slight loss on a ~12 Tflops XB2.  And I don't think Sony wants to risk that.
