I'd imagine it'd be competing directly with the likes of Raspberry Pi 3 Compute Modules. And the RPi3 CMs don't seem to be as popular as the RPi 0 so far. And that's given the RPi was super popular, and was known for their amazing community and commitment to connection standard, support and production.
This is even more hardcore than the RPi 3 CMs, and more expensive. Seems like you have a brave team to tackle on this pie.
