Future of DVD-A

Does anyone have any views on the future of DVD-Audio? I've recently purchased an Arcam DV-79, which I use as a dvd player and cd transport for my Bel Canto II dac. It is also a DVD-A player and I am interested in using it for this purpose.

However, I don't really want to go down that path if I'm just going to end up buying a few dvd-a discs and then having the format disappear. I've seen a bit lately about the demise of sacd, but is dvd-a also a victim of that format war?
