What do you think is blu ray future format or will this be the same as SACD to CD, where CD could not be superseded?

blu ray is here to stay in my opinion.

Players are cheap now and you easily find them for 200$cad or less even and all new movies are available on blu ray. I bought mine on boxing day for 188+tx $ canadian ... a steal.

Sure blu ray disks are more expensive than regular dvd's, but I don't buy any new releases the day they come out anyways. 

Dvd rental stores now carry blu ray movies (up to 5 pcs per new movie coming out, and they're almost always out..) I buy them about a month after their initial release date at about 21$ new or from my rental place (they sell the ones they rented out for about 10$).

Still having a physical copy of something just can't be beaten.
The whole digitial thing with downloading at excruciating slow speeds and with errors and hard disk crashes etc .. is just not my cup of tea. I spend enough time on my computer every working day, so I don't really feel like spending more time with downloading stuff etc.......for entertainment.

I just love being able to slip a disk in the player and press play and we're up and running ....

Just my 2cents .....

O.

I think it will be somewhere in between. SACD required a bigger investment in gear beyond just the player. Audio & video were only starting to integrate so multi-channel amps and extra speakers were daunting. Combine that with the slim selection and you had a flightless bird. 

Blu-ray benefits from the equipment being largely in place. People were upgrading to HD tvs and multi-channel sound already. There is also more content available.

Digital video is nipping at its heals, though, so it won't likely reach the mass proliferation of DVDs before it dies out. 

As far as buying one, though, I think it's smart to do so if you watch a lot of movies. DRM, not technology, is the major hold-up in making movies as easy as music. Once studios figure out their role in the distribution of their content, we should see some much easier solutions than what's out now.
