I can't really say i'm looking forward to DDR5 in all honesty. It'll probably be the same as DDR to DDR2 to DDR3 to DDR4. All of the early sets had rubbish timings and it wasn't really until about half way through each cycle that we got fast ram with tight timings. I don't see DDR5 being any different.
Yeah I could see early adopters getting burnt.
Not only are they getting first gen sub optimal DDR5 kits but it's launching with Zen4 - a new cpu on a new socket and new chipset platform - prepare for bios bugs galore again. I'm waiting one or two years after before I jump in, by then the platform will have matured and DDR5 quality improved
