By this logic Microsoft should have a 27TF Xbox in 2020PS5 in 2019 for me is a given. If we assume same rate of improvement.
2013 : PS4 (1,8 TF)
2016: PS4Pro (1,8 TF * 2,3 = 4,2 TF)
2019: PS5 ( 4,2 TF * 2,3 = 9,7TF)
However, moving from jaguar to Zen will provide a very nice power increase from Jaguar. Probably Sony will produce a console in the 10-11 TF range.
That's only a 5x increase. Too anaemic to be a good new generation.2013 : PS4 (1,8 TF)

If VR is the next big thing, then frame rate will matter. Eventually VR will be the "thing", but we aren't there yet. When it happens I don't really know. The issue is that it takes away from consoles being in the living room. there are some issues to figure out.Keep seeing arguments that consoles not hitting 60fps is a primarily a cpu problem and not a developer choice. Zen in next gen consoles isn't a gaurantee of 60fps. Developers are still prioritized graphics in in single player aspects of games.
The only way I can see 60fps becoming standard is if 30fps starts detracting from the increasing realism of games. Though I still think animations are currently more of a problem in that aspect.
Well, power is king.
7nm on AMD is coming the end of 2018. Navi Gpu will launch the beginning of 2019 with upwards of 20TFlops power. 2020 ps4 with that power, 2021 xbnext with 25-30Tflops, both with have some for of HBM and 512+ gb/s busses.
Scorpio is so powerful though, it does make it difficult to overshadow by a significant margin within the next 2-3 years. Lets say Sony decides they want PS5 in 2018. Can they markedly beat 6 TF and 12GB RAM? Not that I know of, it would be pretty difficult squeezing 8-10TF and 16GB RAM in a console anytime soon for a decent price.
PS4 had 1.8TFlops near the end of 2013 when AMD released a 3.7TFlops GPU for the PC on January 2012 (and the PC had the 5.6TF 290x by end of 2013), 20TFlops on the PC could easily end with a sub 10TFlops PS5, I doubt that Sony wants the 300W style monster GPUs added to their console, specially with people so keen on keeping the same price ($399)
starting from the Pro, I think it will be difficult to have something that looks like a proper new gen for regular prices in 2020, it's probably realistic by 2020 to have a 3x faster CPU around the same power, but the rest, not so sure.
And the fact that AMD was stuck on the same node and architecture for so long has nothing to do with this?
