Here's a wild idea: build the PS5 with expandable memory. I know that goes against the console edict of "fixed hardware/closed box", but we've already seen successful mid-cycle hardware upgrades (XB1X, Pro) that co-exist seamlessly (in terms of games) with their lower-powered siblings.
So why not build the PS5 with on-board 16Gb RAM, and then have a user-upgradable DIMM slot so that down the road when Sony and game devs need/want to support it, users can expand the memory to 32Gb. Newer games could take advantage of the doubled RAM for all sorts of visual and performance improvements, while non-upgraded consoles would maybe experience longer load times from HD, less-detailed texture maps, etc.
And speaking of the HD, I'd much rather Sony invest in a high-performance interface like M.2 to improve data throughput than try to stuff 32Gb of RAM into the console at launch.
