Yeah Epyc/SP3 has twice the number of memory channels vs TR4, much more IO bandwidth and most of the market is aimed at dual-socket servers, with a fair few other platform features that don't exist/make much sense on TR4 besides the lack of SP3 consumer boards of course and the inability to get Epyc CPUs actually working in a TR4 board which is very unlikely to change.
Just like with TR4 and AM4, I think they've differentiated the sockets well enough to have core count crossovers while still maintaining a clear performance difference in their target workloads and a big platform & feature difference.
Since they already have 32-core Threadripper parts and want to go higher I'd think 48c was a minimum we can expect, and the only thing that would rule out a 2990WX style 64-core part would be memory bandwidth limitations imo as that part already made big sacrifices to single core performance for the specific target workloads while matching their Epyc line up.
