I doubt they'll give us an idea of how long they'll support AM5. They'll probably go with the usual "many years to come".
As for the 3D cache versions, I actually don' think they'll talk about them. So far they've only appeareed in rumors andin nothing else, unlike the other CPUs from which we've seen some leaked benchmarks or entries in some bases. AMD could use them as a mid-cycle refresh next year.
But we'll see how it goes.
Please excuse my bad English.
