iirc. there were rumours about Hyperion considering releasing 0x0-only version of AOS4.
Of course, that wouldn't be "full" OS4, unable to run PPC code (Without PPC at least), but would include some of changed parts (like user interface) that can easily be (also) compiled for 0x0
But of course, that's something that would likely happen (if it would) after release of PPC version...
