It was successful, which means they'll do one run then never make any again.
EDIT: AmigaKit needs to start buying the rights to manufacture and distribute these things, so that we don't have to be beholden to the whims of finicky designers.
Well, sometimes it's that, but it also has a lot to do with supplies of components drying up. I think the Subway was designed almost a decade ago and the only reason the last production run was possible was because the developer of another (unreleased/incomplete) Amiga USB card sold his out-of-production parts to E3B.
We'd all love to see more availability of Amiga stuff. It holds its value incredibly well, so there's no risk of a manufacturer eating the costs of unsold product from a larger production run. The challenge is that the return on investment is years long, so developers/dealers may not be able to wait that long to recoup costs, or may not have the cash on hand to order a larger quantity in the first place.
