Apollo Core already includes a special MMU, as far as I know there are no plans for a Motorola compatible MMU. As for hardware FPU I don't know, it may or may not eventually have one so if that's a deal breaker either wait and see or stick with Motorola hardware.
'Special' MMU, sound SO useful.
And yes, the lack of floating point functions is a deal breaker (for that matter, no matter how 'special' the MMU is, if it isn't Motorola standard there is software I want to run that isn't compatible).
So, as before, unless all you want to do with your Amiga is play games, you're out of luck.
