No doubt a "real" hardware alternative is what most people want. I think in the end it's just going to be the OS that will have to draw users back in all the while running on x86 hardware. This is the only way to get power and expansion cheaply and immediately into the hands of old and new users.
Will the OS alone be good enough to do just that? It'll have to be because developing, maintaining and evolving a plarform over time takes a lot of money. And all alternative Amiga hardware platforms have either died or had a tough time even getting started.
I think long-term we won't see any surviving hardware solutions for the Amiga but the x86 option. These PPC mobos will eventually dry up unless there is a huge PPC Linux market just waiting on these boards. I doubt that. Linux is already well established in the x86 platform.
Support for Linux PPC just isn't a priority for any developers. Software or hardware, there's not a big enough market to sustain either an Amiga or Pegasos PPC platform over time.
