From what I understand, the 9000 will be a combo DVD/SACD player (which of course will also handle cd's). Sony is planing on dropping the price on the CDP777ES and leaving the SACD-1 alone. I'm not sure about the fate of the 7700. Of course the main thing to be excited about (imho) is a DVD player with Sony's five year ES warranty. Again, I'm only 80% sure on this information
