If I were them, I wouldn't say anything until the final days of the merge window, when they need to merge in compiler support for their first CPU to support AVX10. Until then, they wouldn't want to give anyone a reason to hold off on further AVX-512 optimizations.
I'm pretty sure AVX10 support from them is a given. It will be interesting to see if they carry forward AVX-512 support, or withdraw it from at least their APUs. I wonder if it would make any sense for them to have a core that supports AVX-512, but only AVX10/256, like if they do their half-width pipeline thing.
One reason I'm fairly confident AMD will join the AVX10 bandwagon is that the x86 Ecosystem Advisory Group seems like a response to a rebuke from big hyperscalers for Intel and AMD to stop playing games with the ISA. I think their biggest customers told them to get on the same page, or risk losing out on future business. So, AMD will come along on this, and the real questions are just about the 256/512-bit thing and on which products, plus whether to support AVX-512 on APUs and C-core server CPUs.
