Wouldn't it be great if the hardware obstacles to going back to (or remaining with) 680x0 based code were eliminated? I mean if FPGA's, or something similar, but not yet invented were to come along that could run a 680x0 core at speeds where it did not matter anymore, speeds that could rival, or surpass current and future x86 designs at lower power consumption and could also provide access to modern peripherals, like USB, Firewire, SATA devices, PCI-e slots, or what ever comes to replace these standards.
What if, in the future, a movement backward to simpler programming techniques like coding for the 680x0 was claimed to be by many programmers, were to become more popular if the hardware was available to make it competitive with other designs?
You must admit that there were many more "Bedroom Programmers" back in the heyday of the 680x0 Amigas than there are today.
Then again, perhaps ARM is already moving in that direction and will make such a comeback of 680x0 coding remain with only the retro crowd.
