I wish them the best, but they must be warned that a lot of people will express scepticism about their project because of the history of such projects, Minimig and FPGAArcade aside.
It's really early for them to announce anything, so to write about 400MHz CPUs executing two instructions per second on the FPGA is a bit presumptuous! I hope they achieve it, but years and years of optimising existing 68k VHDL cores (TG68, etc) has only resulted in a 68020 compatible core with around half the IPC (judging from the Vampire 600 benchmarks) of a standard 68020 (luckily able to run a lot faster, to make up for the implementation shortcomings).
What is good is that the company they work for needs the boards for its in-house projects, and thus the boards will exist eventually, it "only" needs the Amiga custom cores to be implemented. I presume there is a base board, and there will need to be an Amiga I/O board that plugs into it to provide the Amiga ports (joystick, audio, etc).
