I think with the dev kit you're mostly paying for the motherboard-type thing and all the software.

The module itself doesn't seem that expensive, given that you're getting a top-notch ARM SoC. Personally I'd be interested in a group buy when it gets released (early next year, for $299 in 1k quantities).

The only Cortex-A72 chip that I know of is the MediaTek MT8173, and the GPU on that is nowhere close to a Tegra X1. So it's not like this is a previous-generation chip, despite being close to a year old.
