I own players of both formats, so if one format fails I'm still covered and in the interim I'm enjoying ALL of hte great HD movies that are available. Let me tell you, the difference in HD and SD dvds is incredible. The diffence is much more signficant than between redbook CD and SACD. Also, both of my players are great upconverters of SD dvds, so if one format fails, I can always use that player in another room, so its not totally a boat anchor. I have about $800 into both of my players combined, but I would not put that much into a single format until the war is settled. I would love to see what Denon can do with Blu-ray, but not yet.
