The best thing to happen to the Amiga is freeing it from custom hardware (as the AmigaOne has done). I'd like to have all the money I've spent on custom Amiga hardware since I first got my Amiga 1000 back in the '80's. Recently I paid $160 for a crappy little scan-doubler box for my classic Amigas that doesn't even work very well. People whine about losing the custom chips. A new custom chip-set would have to do something more than the zillions of PCI video cards out there. It makes you wonder what that would be and why bother?
