It's not totally gone yet but news isn't good for Sony's UMD format as detailed on this Yahoo page
. Now I'm probably one of the very few in the US that loves the minidisc format but even I could see the UMD format was going to bomb. If they didn't keep it so closed up and offered recording capabilities it might've had a small chance. In any case, could this be a sign of what Blu-ray is going to be like?
