Too bad there's no decrease of DRAM prices soon.
Sure there is. At least in the US, you can get a 2x8GB kit of DDR4-3000 for around $130 now, whereas it would have cost around $170 just a few months back. So, RAM prices have been getting quite a bit better than they had been for most of the last year.
They are not down to the level they were in 2016, but that pricing was likely unsustainably low, and was brought on by overproduction. Sure, you may have been able to get 32GB then for not much more than what 16GB costs now, but even today 16GB is more than enough for games and the vast majority of applications, and will likely continue to be sufficient for the next few years.
At least pricing is getting back down near 2017 levels now. And looking at recent pricing trends, I wouldn't doubt if it drops lower still in the coming months.
