The empeg is discontinued, too, but it receives updates only because it shares a codebase with some of the newer products and they can use us as unwitting beta testers for new code.
At least, that's what we tell everyone. The real reason it receives updates is because we've all got one. Nowadays we've all got Rio Centrals too (they found some in a cupboard when closing down Sonicblue) but it's been so long in code terms since anyone tried a Rio Central release from the code trunk that it seems too much like hard work to try and update it. (Though red flashing lights still go off if it fails to compile, so we know it'd only be a question of not working. And a rip-to-flac-and-vorbis Rio Central that supported big winchesters would rule.)
