If the spinners do decline (and there's not much evidence of that at the HD end) won't streamers emerge (e.g. Dune Prime) that will do all the decoding?

Personally, while I never spin a CD these days, I think I will be relying on my BR discs for a quite a few years. Average internet speeds (at least in the UK) make downloading hi-res material impractical. I could buy the movie on disk and transfer it to a server but I'm not sure I see the point - there are very few films I want to watch more than once a year.
