Interesting responses to this thread so far, maybe I'm just more willing to trust a dev who's created games I've found more interesting and fun than most others of the sort. The criticism laid here are the same criticisms I shared with regards to the XO and PS4 at their release.
I hope we get a more noticeable and interesting leap in overall fidelity than we're expecting, but maybe not if we're to rely on Platinum's opinion.
The only thing you need to know is that Navi is marketed at AMD's E3 reveal as 1440 GPU card for PC... And the TDP for the full fat 40 CU Navi chip is drastically higher than the chip used in a X1X which MS worked their a** off to work on a console level of TDP so any console using the Navi architecture would have to cut corners to even get the Pro which is a sub 9TFLOP GPU that is only a little better than a Vega 56.
4K/30 with Ray Tracing is not going to happen without them lowering settings drastically compared to the PC Ultra settings.
Next generation has the potential of being the worst performing one of all time once less capable developers start to adopt ray tracing for their games.
NAVI CU contains double texture filtering units when compared to GCN CU in X1X GPU i.e. 2X raster hardware vs compute.
NAVI CU contains double ROPS units when compared to GCN CU in X1X GPU i.e. 2X raster hardware vs compute.
MS need to worked their a** off to fit RDNA 2 GPU into game console TDP. Scarlet's APU is about 380 to 400 mm2 size.
I imagine if Sony opts for no hardware accelerated Ray Tracing that they will have a substantial advantage in performance... I hope MS knows what they are doing, a 8 CU count drop just to get ray tracing will cost them in performance in non ray traced games which has the potential of being the majority of games for the next 2 years or more.
Either way I hope they both do adopt hardware accelerated approach as it will help push ray tracing optimisation and development.
I don't think we will see anything more than 4K/30 for the high majority of games but better graphics and some ray tracing features here and there with faster load times.
Zen v2 + NAVI 10 already consumed 321 mm2 while Scarlet's APU is about 380 to 400 mm2 size.
TSMC's 7nm+ has 20 percent transistor density and 10% performance uplift or 15% power efficiency increase.
AMD plans to release "Zen v3" and "RDNA 2" next year with TSMC's 7nm+ (cited AMD's PPT PR road map).

My observations with Zen v2:
One of AMD's approach to reduce CPU latency is to increase L3 cache storage size and rename it as "game cache".
As you may know, Zen v2 still has Zen v1's 4C/8T CCX design with a new interconnect between the two CCX modules. AMD "bolted-on" a large 32 MB L3 cache which can result in traffic reduction between 4C/8T CCX modules, hence reduce latency. This is a brute force method to reduce latency instead of building a native 8C/16T CCX module. The large L3 cache is integral to Zen v2's latency reduction measures, but semi-custom Zen 2 could reduce L3 cache and take slightly higher latency hit.
My MS's release pattern observations:
For Xbox Scorpio
Both PS4 Pro (Nov 2016) and RX-480 (June 2016) was released during the same year 2016, hence silicon maturity and TDP scaling between products are similar.
Xbox One X was release on November 2017 with improved performance per watt when compared to 1st generation Polaris based silicon maturity.
Xbox One X GPU (GCN 44CU ASIC)'s 6 TFLOPS base clock rivalled AMD's RX-580 (GCN 36CU ASIC)'s basic 6 TFLOPS in boost mode while X1X's GPU consumes less power + 2MB render cache with ROPS change + 4 extra GDDR5 chips when compared to RX-580's 185 watts.
For Xbox Scarlet,
RX 5700 XT was released on July 7, 2020
Xbox Scarlet's planned release is November 2020
Microsoft's Scarlet development and release plan is the same as RX-480 to Xbox Scorpio's release plan.
