It is all crazy Pactrick. Imagine what happens in natural disasters, a major solar storm even, or war, lots of way to be cut off or closed down, not just legal intervention. If there is a legal dispute between companies on copyright ownership, even on contract to use copyrighted material, even just a single frame of a accidentally filmed copyrighted work in a movie, given a sympathetic judge, in future it may even be used to shut down a site with 100 million + users, with the way the law is going, talk about service interruptions. There will be new insidious ways to wage corporate battles. The studios have to realise all this stuff they are supporting can be used very wrongly even against them, and once court battles go into the hundreds of millions+ things will get even more obvious. Like the electronics industry IP battles (and remember, future owners of studios from other industrues, are free to bring this mentality with them) where we get some litigious players that think they should own everything, even slight styling, one side gets a bit, or massively, greedy, another gets offended, then it's on for the next x months or years, but unlike electronics and patenting, to do swift damage and cost a lot you will not need little money to do it. Imagine if dense people passed a copyright law where you could potentially close down a whole movie release or cloud movie site because an arty restraunt owner designed a unobtrusive, but unique, rubbish bin to put out side his restraunt on the pavement, or a window display, and decided to have a go. I could design a rubbish bin and get Asian manufacturers to use it for cheap rates so evtually it comes up in film. I think this whole thing about the Hollywood sign is also rediculouse, if it is a public display / landmark, common object, you should be able to have it in shoot. These are why you are carefully designing laws not to be too expansive, and why business should be too, people are crazy enough to do things like this, if you let them of course.
Another craziness, is thus talk of getting rid of tapes and disks, to use hard drives to archive your movie footage. The surfaces of dusks are prone to deterioration of the recorded data, or they were years ago. If you drop one, you might crash the head and loss data. When the custom electronics in the drive age and faulter (notice I said when not if) you then have a potentially very difficult and costly task of trying to figure out how to recover that data. Flash is another prone to deterioration. If you drop a fireproof, magnetic field resistant tape cartridge, what do you have, maybe a/broken cartridge in a archival tape format that can be recovered easily that will last many years. Dusjs are a bit more prone to damage, but have similar advantages. I did some theorising for designing new tape and archival systems in the past. You can record onto a medium with longer archival life and have a mechanism for data recovery, I came up with a mechanism that would work into millions of years. Tape is far from fully developed as well, forget even your mukti terabyte holographic disks, the mechanisms I came up with can far far exceed it's storage density for cartrudge footprint, many times over. As for longevity, that really depends on medium used, which affects recording density, so there is some trade off, and I am not saying I can achieve that density and thousand year plus archival times at the same time, but I should be able to make it durable format in handling. As ussual, no magic, just brains.
I just realised Stuart said redray will also be on physical format, great, great, great. I had a business scheme ages ago, you buy the cloud service and can get a disk with that. For copyright reasons the disk maybe sent out to you after the first 6 months of release with all other purchases for the month, which gives time to maximise revenue before a pirate can lay hold of a library disk (not that they can merely copy the lower quality stream from the cloud anyway). I know I am giving away strategy here, but also establishing a moral prior art date (the patent law sucks). Many businesses have stratergies, schemes and models that suck, fashionably not seeing the dimensions of the problems or of human aspects, or of the future, or how to handel them or design products, they really need to talk to people like me first that see these things.
