Amiga OS4 will die a slow and painful death (or substitute 'is dying'). They should just release it as open source.
That will never happen do to who owns the IP. We were orginally told OS4 was from 3.x source code and then we are told OS4 kernel is not from any Amiga IP at all. Which ever the boingball bounces, it's not going to be released as open source.
