Q: What is Sony Pictures' position on upgrading the Blu-ray specs to put 4K and 8K native video on a BD disc (ultra-high-def specs are 3840x2160 lines of resolution for 4K and 7680x4320 for 8K, current 1080p specs are 1920X1080)?

I posted the data rates in the past, but you can read the blog from Hitachi.
NHK openhouse 2012 in May.http://lcjapan.com/
"Now, Blu-ray might get there–it’s 25 GB per layer is already at 100 GB thanks to 4-layer discs, and 10-layer discs are not too far off. However, it’s not just the capacity: it’s the access speed. If the media can’t send the video data fast enough, it won’t work. And the guy I spoke to at NHK said that even with upgrades, Blu-ray just won’t be fast enough." There is photos on the liink with holographic storage, and thin disc alternatives. NHK is developing for 8k, but there is 2 different capacities holographic disc. So, you can draw your own conclusions from this article.
If you have access to journal articles (SPIE is the main one), it says the same thing about 4k bluray.
Marty: As mentioned, the Blu-ray format is well-positioned to adapt to evolving standards. As the future unfolds, Sony Pictures is in a good position with our asset library, given that we already master a number of titles at 4K resolution.Q: I was wondering if you think that Blu-ray is in fact the last physical format or if you see something like SD cards replacing it in the future.
Parsons: I’ve learned to avoid trying to predict the future, but I do think that new physical formats are based on specific applications that mandate their use. For standard-definition, we had DVD, which did the best possible job of presenting content in that resolution. For HDTV, we have Blu-ray, which has enough capacity to present 1080p images and uncompressed sound with the highest possible quality available. Fortunately, if and when 4K begins to make an entrance on the scene, Blu-ray has enough capacity to handle that job, too.Q: Apple has made a point of saying that its new retina displays actually have more pixels than an HDTV, suggesting the picture quality is better than Blu-ray. Do you think Blu-ray will be able to become more high-def with greater resolution? Is there a next-gen HD in the works?
Parsons: We are already at the maximum resolution available for the HDTV systems currently in use around the world (1080p), so the only way to become “more high def” would be to incorporate 4K resolution into the format. At present, the BDA is not working on a 4K version of Blu-ray, but if and when the time comes to do that, we believe the 50GB capacity should allow us to accommodate the much higher data rates that 4K sources require.
