Currently the only real options for amateur off-the-shelf (accelerated) edge ML are the Nvidia boards (but small carrier boards for the TX2 cost more than the module itself) or the Intel NCS which inexplicably blocks every other USB port on the host device due to its poorly designed case. There is the Movidius chip itself, but Intel won't sell you one unless you're a volume customer. The NCS also does bizarre things: the setup script will clobber an existing installation of opencv with no warning, for example.
There are various optimised machine learning frameworks for ARM, but I'm only counting hardware accelerated boards here. I'm also not including the various kickstarter or indiegogo boards which might as well be vapour ware.
There are no good, cheap, embedded boards with USB3 that I can find. There are a few Chinese boards with USB3, but none of them have anywhere near the quality of support that the Pi has.
Then camera support. The Pi has a CSI port, but it's undocumented and only works with the Pi camera. The TX2 is pretty good, but you need to dig through the documentation to figure things out. USB is fine, but CSI is typically faster and frees up a valuable port.
Finally another issue is fast storage. It's difficult to capture raw video on the Pi because you can't store anything faster than about 20MB/s. There are almost no boards that support SATA or similar (the TX2 does), so the ability to use USB3 storage would be welcome too.
If this is offered at a reasonable price point, it could be a really nice tool for hobbyists. It looks like they're trying to keep GPIO pin compatibility with the Pi too.
Hopefully it will, since the voice and vision kits on the same AIY page are sold for $50 at Target.

Single units are listed on this page, e.g. mini-PCIe board with Movidius VPU for $79: https://up-shop.org/25-up-ai-edge
I was referring to the Movidius Dev Kit which exists, but seems impossible to buy as a consumer.
There's a review here though: https://fossbytes.com/rock960-review-affordable-six-core-arm...
