They've said no moe for 3.8, and since they're already releasing a qwen4 early preview, they're probably focusing on that arch going forward.
3.8 next is not really a 3.8 (but I guess they had to disambiguate from the previous next). It's a preview of qwen4 architecture (and it is an moe + ngram), released early as a preview, and to help the community sort out inference before qwen4 releases.
