FPGA Arcade have a board for ~200 EUR that will proberbly offer some nice re-implementations of Amiga in the following months.

I guess you haven't missed Minimig ..? ;)

Looking at the fpgaarcade schematic one can see that a XC3S1200E-FG320 FPGA used. And that there is no CPU on the board.

It's possible to squeeze in Amiga custom chips + 68000 softcore in the Minimig XC3S400 (barely?). Which has 3x less "gates". So this XC3S1200E FPGA should be able to handle both the core Amiga custom chips and standard 68000 cpu. However I think it's likely possible to implement AGA and 68020.
I hope the dynamic-ram memory is fast enough to update the required resolutions. The 16 bit wide DDR type should have no problem to handle this however at ~264 Mbyte/s.

So the path to Amiga 1200, or maybe even A3000, A4000 is open. I miss the onboard Ethernet thoe.. :P
