I guess I'm looking at something like the B7 or C7 (hoping for the best panels/picture quality here) and how the prices fell after their initial release to be the current $3000. At release though I believe they were probably at least $1000 more back in February? Maybe by mid to late 2019 or late 2019, I'd guess $4500ish (assuming a mid 2018 release).
More than happy to be totally wrong though.
Acer and ASUS delayed their 27" 4k monitors to 2018 as well. Apparently they're supposed to be in the $1500-$2000 US range. Not sure I'd bother with the 27" if I can pay the difference to get the 65".
