Don't count on it. I emailed their engineer, Michael B. Tretow, about the possibility of surround mixes of ABBA's albums being done, and he was very adamant that it won't happen. He explained that he, Bjorn, and Benny worked very hard to create the sound that we hear on the albums, and that B&B are absolutely NOT interested in remixing in surround. There already exists a box set that has all their studio albums, remastered, and a disc of bonus tracks The set, "ABBA- The Albums". is quite good. I doubt they'd be interested in doing even hybrid stereo SACD's; when I asked about it, he didn't say.
