If anything, maybe next media format would be what we last expect. SD cards are already getting into the house of hundred of gb ( ultra-expensive, nowadays). But if they decide to use a memory card for holding the 8k files ? From now, til 4k get some adoption , til 8k, there should be at least 10 years in the process.

I doubt that SD cards will ever be as efficient price wise as a disk. You don't have the overhead of circuitry with a disk.

I imagine that at some point the disk will be stationary and the laser will be the part that moves by mirrors.
Combine http://www.dailytech.com/Scientists+Create+360+TB+Superman+Crystal+Discs/article31933.htm with http://www.iflscience.com/technology/worlds-fastest-camera-takes-44-trillion-frames-second, direct a laser beam into a cube and analyze the light that comes out to retrieve your data.

Although I see optical holographic storage is already old news

Maybe SD cards based on that technique will be the future.

It's the fight for time and space. If a TV resolution end point is decided by the majority. Movies/shows will stop getting bigger. And then space won't change. So if SD cards hold out as a use for that time. They will be cheap to be used as physical media. But too many if's everywhere.

Sure I don't see any more benefits beyond 8K for current tv sets, yet that's only the beginning. Holographic displays already exist and those need tons more data to describe the full 3D scene. There's still a long way to go before we're standing inside the holodeck. Imagine a recorded concert where you can actually move around the stadium in your living room, and the kind of data storage needed for that. That definitely add rewatchability to recorded video.
Just daydreaming about the far future lol. Yet considering how fast things are going I might still see holographic tv become a reality :)
