IMO both will survive for a very long time, but neither will "thrive" . I went with a universal player, so I can enjoy Stevie Ray Vaughn on SACD and Steely Dan on DVDA. Hybrid SACD's give SACD's an edge, but most DVD player's will offer DVDA capability so who knows....But if you want me to pick a winner............It will be Redbook, the masses barely understand pro logic, let alone 5.1 or 7.1 channel inputs..........
