YES, AMIGA BRANDED MACHINES IS THE ONLY WAY THAT AMIGA WE'LL EVER REGAIN FULL IDENTITY, even if the machines can be purchased only via the internet for the time being.  Porting to this or that machine to be installed by this or that hobbyist is small thinking, IMO (but it still beats being held hostage by AI).
If your business is the OS, as it is for Hyperion, then it makes sense to get the OS on as many computers as possible. If I could throw WB 4.1 on one of my old Intel PC's sitting around, I would probably buy it and do so but I am not buying a PPC system just to run it. 
Amiga branded system, yeah that would be nice but I don't see it happening.
