If it is cycle exact hardware, what is the difference? He can't use the original chipsets because of copyright or patent.
The BoXer was going to have the AGA chipset put in an FPGA.
If Commodore had done a next gen Amiga, AGA and OCS would have been turfed (or really just crammed in somewhere for backward compatibility) in favour of chunky mode 24-bit graphics.
I am tolerant of those who like the old hardware, however I wish to have something modern. Old rusting and failing Amigas would cause me sadness and not joy.
