I think shininess is fairly likely, because they are collaborating with Teenage Engineering, who have a reputation for making nice things like the OP-1.
Homebrew is much more questionable. On their “media” page they imply that an SDK is forthcoming, but they certaibly don’t make it as clear as I would like.
At any rate, the point I was going for was less that I am 100% behind this gadget, and more that I think there is room for more options in this realm, and this ticks at least some of my boxes.
