The next box could be:
* Spartan-3E with softcore MC68020 + AGA
* Ports as Minimig1 +
* DVI/HDMI, SPdif, Ethernet
After that:
* Virtex with builtin PPC, with softcore MC68020 + AGA
Using the PPC as "accelerator"
RocketIO as SATA disc controller.
* Ports as above
Just free thinking.. :crazy:
Don't forget issues like transmission line effects within the pcb, multilayer, oscilloscope debuging, BGA-hell etc..
Otoh, a suitable developerboard can proberbly do it all without the fuss. Just needing some creative HDL code :-)
