I think Blu-ray will be here for good 5 something years. Untill ISP can give us faster downloads so everything goes digital. Things will not go digital for a while because it will take forever to download bluray quality movie.
Even more important than that are some of the other points mentioned above-including that you can't actually buy video online yet.
To most people the diffrence between blu ray and DVD is nothing its still a disk it all looks the same. thats the thing with DVD it looked totally diffrent then VHS.
There's a bigger jump between DVD and Blu Ray than between VHS and DVD, though there might be a 'diminishing returns' type of thing going on for some people.
I hope it goes all digital
What does this mean? Our media has BEEN all digital for YEARS now.
