Even if the X is selling more than the S, the point was it doesn’t change the view of affordability. It is also selling far less than the cheaper PS4. Don’t think that isn’t being noted.

As far as “20GB would be a very weird number”, we have 11GB graphics cards. 20 would hardly be any weirder than that. I know, power of two, but we've already defied that.

Doesn't really matter about powers of 2 conformity... Which has typically been AMD's memo, not nVidia's.
Each chip is usually connected via a 32bit memory bus... Memory transactions tend to be parallel.

But 20GB would mean a 320-bit memory bus... (If we assume it's using 10x 2GB chips) Which is actually less than the Xbox One X. (12x 1GB chips @ 32bit = 384bit bus - 12GB total.)

Still hedging my bets on 16GB though for a base console on a 256-bit bus, it offers the best bang for buck and keeps complexity down... The Xbox One X was a "premium" console after-all, which had more memory chips, wider memory bus, more PCB layers and a really (surprisingly) good power delivery system to power it all, none of that comes cheap.

And 16GB is actually a fairly chunky amount of memory anyway, developers can do allot within that amount of space if they leverage various technologies.
At the end of the day... Microsoft and Sony need to weigh up the Pro's and Con's of additional 4-8GB of DRAM... Or less Ram and more CPU/GPU performance... And I think the GPU is going to be at the forefront considering how stagnated AMD has been on that front... So they will likely push that envelope.. It's also the biggest sell. - People tend to be focused on GPU flops over anything the CPU or Ram does.

We should also expect the OS memory consumption to increase as well... A 4k User Interface isn't exactly going to be light on DRAM, which is why the Xbox One X's User Interface still operates at 1080P.
