AFAIK The sparc processor is something like opensource so anybody can make is own processor but i don't think it is the best processor for the amiga.
Sparc or Mips are fantastic processors but they are very specific, their future developpement are uncertain mips are unfortunately still dead, sparc is still alive but sun sell more & more x86 hardware.
I think the only mean to save Amiga is to open it to x86 to be abble to live on any PC compatible.
Amiga only lives through their early fan but who will pay thousands $ for an old/new machine ?
I really love Amiga but I don't have enough money to buy an Amiga One witch i can only use with AmigaOS 4 or Linux.
But if I can run it on a out of box PC I willl use it sure !
