Dodo time?
It's well past the window for becoming a dead format:
* It's the only viable format for hd content. Online streaming is shit, you need a 4GB+ h.264 file for a feature length video to get something worthy of the hd stamp imo, and like hell am I downloading 4GB+ if it has copy protection or becomes unplayable after x amount of days.
* There's plenty of players in the wild.
* It's easy enough to copy the discs, which is a major plus.
* Do you see anything else on the horizon within the next 5 years that can better blu-ray? The next optical format may never arrive (at least not in that window), and transferring via a solid state format similar to an SD card or ssd seems unlikely until 50GB+ of data can be crammed into a small space with fast access speeds (90+ mbits/sec), without melting the player/card, produced cheaply, and with all the film/tv producers getting on board with the idea. Again, not in the near future.
There's a double standards issue here, in physical form a new hd format needs to be at least as capable as blu-ray to deliver high quality content (50GB+ capacity with a video format at least as good as h.264). Anything else is a step backwards. Even considering a 4GB feature length h.264 video to be hd, I can't see streaming to cut it for most for the foreseeable future.
