Perhaps you should read what actually gets said by the Natami team and not rely on EAB rumours:
"D - Custom Chip complete redesigned 600 MHz - Several GigaHerz"
"Option D is too expensive for the AMIGA market."
An Altera Hardcopy version of the N68070/SuperAGA isn't likely to cost $300,000 USD for one chip, that seems to be the most likely route they'll take with the design.
