Why would anyone buy 13th gen either if 12th gen had APO? It's often cheaper and the difference between a 12700K and 14700K was basically 7% on average in the CPU in general, not just gaming
Given the prices of 12th gen are typically lower, it would make more sense to spend less and get better price/performance
If it does happen, I would assume that it's because of bad bins from 5600X3D and 5800X3D production, the 5500X3D would probably be another limited time Microcenter thing, the 5700X3D would probably stick around for awhile considering the supply of 5800X3Ds seems to still be very steady.
