Lots of people building PCs are going to be buying DDR5 (just as many have already been doing), so for these people, the question is AMD platform, or Intel?
As prices fall further, the cost of DDR5 will become less and less of an issue to buyers, and people know DDR5 modules will work in PCs for many years to come. People also know that LGA1700 motherboards are a dead end, and that the 13th gen is the same architecture as the 12th, but clocked higher.
I suspect that many buyers are fed up with having to buy a new motherboard and rebuilding a PC, every generation or 2. Lots of people will probably choose a 6 core 7600X (plenty of performance for most users) on release of Zen4 and AM5, and just upgrade every couple of years, the total cost of this will be quite low, and no doubt there will be cheaper CPUs, like a '7600', or '7700' further down the road (as was the case for Zen 3). The other nice thing, is that you will be able to keep using the same AM4/AM5 cooler for future CPU upgrades.
So you can wish all you want that people stick with Intel, but ultimately, some real competition is good news for consumers, and helps to reduce prices. Hopefully, Intel will be forced into designing Meteor Lake's CPU socket to support upgrades for a longer period? Intel hasn't been offering CPU upgrades with a die shrink or new architecture, but more and more, this is what system builders/upgraders will want (e.g. meaningful drop in upgrades).
