r/LocalLLaMA lit up overnight with a wishlist thread for Qwen 4 (66+ points, 100+ comments and climbing). The OP’s wish list is very “local-first”: a 27B with more efficient KV so 128k doesn’t eat ~8 GiB of cache, a Flash variant in the Qwen3.8-Flash-Next style so desktop boxes can run ~125B-A6B MoE, and medium thinking that actually matches today’s xhigh quality.

That framing matters. The community isn’t just asking for a bigger leaderboard model—they want architecture choices that keep long context and MoE usable on single-GPU / unified-memory machines. If Qwen 4 ships dense + Flash + better KV economics, a lot of people will swap their daily driver the same week GGUF/MLX builds land.

Practical note: treat launch-week hype carefully. Benchmark the sizes you can actually fit (weights + KV + overhead), and re-check your stack (llama.cpp / Ollama / MLX) for first-week quirks before you delete the old quant. Wish lists are useful signal for what local users will measure first: tok/s at long context, not only MMLU.

What would make you upgrade on day one—smaller KV, a desktop-friendly Flash MoE, or better coding/tool use at the same VRAM budget?
