So I'm not really sold on the need for an 8k TV (although for monitors potentially useful)...I could see it being useful with projectors for sure (although I think OLED will be cheap enough that I'm not positive projectors will gain much traction).
Does anyone wonder how 8k content would be delivered though? I have 150mbps internet, which should be good enough for it...but currently netflix 4k streams are 15mbps. What does it matter the resolution of the TV if you can't get the content providers to actually up the bitrate!
I can't imagine consumers in general will adopt another disc format. I'm glad UHD blu-ray exists...but the writing has been on the wall for a while with regard to discs. Convenience over quality. Without sufficient demand for discs, and content providers being stingy with bandwidth...I'm not sure how this will get off the ground realistically. I'm guessing this is at least 6 years away though so who knows.
