True 4K Blu-ray - why I will mostly skip if released

[Ruined]

I personally don't feel that Blu-ray 4K is needed to continue preserving optical disc, nor do I think that it will save optical disc if optical disc is dying.

Most people are content streaming 720p Netflix on a 1080p set, so I do not see where 4K will be a huge factor for most people - especially if it is no better than 2k on most screen sizes. In fact, Sony's "mastered in 4k" series may just be good enough for the average consumer that wants 4k content. Sure, its not true 4k but so what, let the marketing do the work.

In fact, a whole 4k new disc format may do the opposite and may end up cannibalizing "classic" Blu-ray due to the "Osborne effect." What if consumers stop buying 1080p Blu-ray discs in anticipation of 4k Blu-ray (which may be some time off still)? And then, what if 4k Blu-ray underwhelms or underperforms? Then you just succeeded in stalling sales of physical media. Again, if it was a guaranteed hit like 1080p was over 480i, its a good strategy. But, if it is a potential flop due to the lack of perceived difference and increased cost over regular Blu-ray, then you may end up doing more harm than help!
