Quote:So theres "NEVER" going to be a 8 layer blu ray disc?
In commercial use, no. I don't think that 200gb optical disc won't be needed in the lifecycle of bluray disc's. Bluray (and hd-dvd) will be sufficient for 1080p material, and only 2 layers are needed. Same thing as it is with dvd's today, dual layer is enough for mpeg2 compressed video. The next generation of optical media (probably hvd -> http://en.wikipedia.org/wiki/Holographic_Versatile_Disc) will have 200gb on one layer (same amount as 8 layer bluray disc), with the theoretical space of 3,9 terabytes.
Large corporations that need to back up data perminatly or for a very long time (10+ years). 1 Terabye clears up server space! 1 TB can also be used to backup statistics and records from the past. Think about how many books can be saved.
@ arcanix,
Technically, a DVD 9 disk is sufficent for 1080p matirial using MPEG-4 with MPEG-2 extras of course.
Quote:ya i heard about those HDV disc they sell for 100$ a piece, i wonder who needs 1Terebyte of space??
Yes, they will be 100$ at first, but the price will come down eventually, just like with all optical media. For example digital movie theaters make a good use for these disc's. Do you realise how much space it takes to storage 4000 something pixels wide and 2000 something pixels high movie with superb quality plus audio. And like diabolos said, big companies need those disc's. Even hundred bucks for a terabyte is fairly cheap, and the physical size is small too.

Well technically even a cd is sufficient for 1080p material, for a short clip or totally crappy bitrate. At least I would like the movie in it's full glory with good bitrate. It doesn't hurt if the extra's are in 1080p too. If dvd9's were sufficient for hd-movies, they would've used it.
