That would be a departure from the norm for Intel.
Do you have any sources? I was unable to find any info on Meteor Lake and board compatibility.
That said, AM4 is a dead end socket, so building right now is a coin toss between the 12900k and the 5950x as far as price and performance. I'm not sure the 13900k is going to be much of an upgrade.
I just bought a 12400 mostly because it was 15% cheaper than the 5600x and it comes with an iGPU. You're right that it's unclear whether 13th or 14th gen will be an upgrade or possible, respectively.
