Bummer. I put a lot of work into learning the 68k in the '030 era when it had become fully 32 bit. In my (albeit limited) experience, I found it to be very comfortable to program on.
This is sad. I really like 68k. It seems to me there was a was a Coldfire cpu that they based an accelerator card on for the Atari. I am not sure how well it worked, but from what I read it had a system to trap 68060 instructions and run it through an emulator.

I don't have a dog in this hunt (I've taken my A3000 as far as it can go), I have no idea how close to production it is, but I do find it an interesting project to follow.
But according to a few mentions in the forums, the MMU is very different from the traditional 680x0s and may be a non-starter for NetBSD.
