Absolute vapor. Wouldn't trust the annoucement as far as I could throw the server it's hosted on. There are apparently still significant problems getting the Coldfire to (properly) emulate the 68k instruction set (so I've heard).
EDIT:
Although I will say that if they've pulled it off, maybe it will open the door for the other Coldfire project - the one aimed at CDTV, A1000/2000/500/600 systems. We can only wait and see...
