I think blu-ray will make it. I was an early adopter and have observed a significant growth over the past year or so. My local Fry's and Best Buy now devote significant shelf space to blu-ray. I get emails from Amazon practically everyday pushing blu-ray. SACD, on the other hand, was never more than a niche product and never gained any traction outside the audiophile community. Actually, my local Best Buy is now devoting more shelf space to LP's than they ever devoted to SACD.
In regard to HD downloads, I agree that is the future, but I believe that technology has some serious hurdles. Not only the referenced bandwidth issues, but we'll have to get to the point that the average consumer has the ability to download, i.e. high speed internet access in their viewing room (or wireless acess) and access to devices to accomplish to the download, etc. For the average consumer, a blu-ray player will be the easiest access to HD movies for the forseeable future.
