I think the Mandrake LINUX will continue to be developed: Mandrake as a company is in bankruptcy protection for now, but sales are OK and they do even make money.
On the other hand Mandrake doesn't do the port to Amiga PPC as wont do SUSE, RED HAT, DEBIAN etc.
They just do a PPC port for the MAC but SUSE already gave up on this one. Mandrake 9.1 can be preordered now.
They do have a PPC version. Only the installer needs to be adapted to the AMIGA.
Someone in Germany did so.
