I think @spirantho has some good points, and I share the views.
In my mind, if a new Amiga branded computer gets avaiable for a low price, people in my generation that used to have an amiga and only have good memories about it, will get one just to see what the fuzz is about. If the price is low enought.
The new amiga is even mentioned in the mainstream IT-news here in norway, thats how strong the name still is out there.
Low end machine = lower price = posibillity of larger user base (of geeks) = more applications = new machines.
But then again, I doubt it will ever be released together with os4...
If they blew it this time, the amiga brand will end up just like commodore.
