Don't be too sad, the Apollo Vampire 68080 "spiritual successor" to the MC680x0 line is imminent, works even in an A1000 and is apparently nipping at the older PPC cores.

The other sad fact was that the M68k line sorta died. Yeah, sure Coldfire was pretty close, but still not pin or microcode compatible. 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.
