No rush to get it on desktop PCs, it's just not needed. I would go so far as saying that needing it on a Threadripper setup would be a stretch. Servers definitely, since DDR5 should bring the possibility of very large capacities per module which will really help a dual socket server packing 256C/512T.
With PCIe 5 and USB 4, both very much beneficial to desktops, as well as laptops and servers, ready to make an appearance, AMD doesn't want to make a socket for just one series of chips like Intel does since they spent all that time bashing them on it, and they decidedly do not want to lack support for those features when Intel implements them. If AMD had created a new desktop socket, AM4+, it'd let them get 2 generations of chips on the same board, -maybe- 3, but the way it is, they've dug their grave with AM4, they're going to have to ride it out.
