The announced remasters on sacd will be hybrids and therefore will also contain the remastered audio on a regular cd layer. So, the answer to the question if it's worth to buy them if you only have a regular cd/dvd player still depends on the actual quality of the remasters, but that also holds if you do have a sacd player. We just have to wait and see, I mean listen. Still, I hope they manage to somehow improve a bit on the somewhat muddy sound of communique and the bit narrow soundstage of making movies.
