Yup. Just because we've reached some diminished returns with graphical performance and things have been stagnant for awhile doesn't mean there aren't big gains to be made in other areas. A lot of people just don't seem to be familiar with where their performance bottlenecks lie. I thought it would be fairly apparent by now, with the public outcry and discourse surrounding Cyberpunk 2077 on PS4 and XB1. Faster processing and SSD read speed IOPs lead to improved (modern) performance.
SATA SSDs have been aging on PCs for awhile now and we had previous gen consoles running on spinning HDDs

I mean, my previous PC I built in 2012 had its OS and main games on an SSD.
It's just too bad that these consoles would have been $650-$700 if they had included 2TB NVMe SSDs.
