Is there even an inkling of a plan to go from “dev kit” to “widely available consumer product?”

It’s not a dev kit, it’s meant to be a regular PC with upgradable storage, RAM, and PCIe slot for $120. Milk-V and other RISC-V companies already have widely available consumer products (Milk-V Mars, Banana Pi, etc.), they’re just usually SBCs because that’s what’s easiest to produce and RISC-V is early in development. Remember that the first standard with Vector instructions just came out a few months ago (RVA23), and there’s no point in trying to seriously compete with X86/ARM PCs until you have that.

Even a lot of x86 devices are going to the soldered everything approach.

That right there tells you this is not a RISC-V/ARM problem. It’s just that everyone knows on-SOC memory performs better than DIMM, and manufacturers are starting to offer these to compete with Apple M chips.

Milk-V Oasis Mini ITX board was going to have replaceable RAM, M.2 slot for SSD, and 4x SATA slots. The only reason it didn’t release was because of Sophgo sanctions (They make the SG2380 which was the Oasis was based on)

That is until they kicked everyone out for being “nazis”
