Looks like OS4's days are officially numbered.
OS4 is already dead. For the last seven or eight years, it has gone literally nowhere; Hyperion are unable to pay anyone to touch the code, even for new hardware, despite several squeezes and a moderately successful UAE/price drop combo. A-Eon have been nibbling at it, trying to become the defacto owners, and Hyperion (or possibly just Ben) have been resisting.
Now it'll probably just end up in legal limbo forever.
