He's right. The NatAmi will have a much larger FPGA than the MiniMig or even the Retro Replay board. It will probably cost around 750-850 Euros for the prototypes and only after the bugs are worked out will we have a Altera HardCopy version of the FPGA made (assuming that's still the most cost-effective technology for making fixed-functionality chips).
There are alternatives with probably lower setup costs than Altera Hardcopy:
eASIC and
ViASIC.
