I think it is strange the they dont also include a classic amiga built on todays standard and a system like natami / fpga amiga would be perfect for those of us who is not millionaires yet! 
An FPGA A1200 would be nice, but I don't know if that's possible, not knowing much about the limitations of FPGA. I assume that it is slower than conventional ICs, but maybe that doesn't matter when you are implementing a 14 MHz system.
