Oh and now people are trying to push 4K TVs and 4K blu-ray onto consumers, I wonder how many people would actually fall for it? Regular blu-ray is hardly selling, and now people are suddenly expected to upgrade their TV and blu-ray player again? I don't know how much is at stake in this department, but Sony's plans for blu-ray definitely failed to live up to DVDs.
As for 4K, Sony (being one of the main Blu-Ray proponents/founders) and Microsoft should have seen that Blu-Ray 4K coming very soon (It was officially announced a few weeks ago http://www.cnet.com/news/4k-blu-ray-discs-arriving-in-2015-to-fight-streaming-media/). I wonder if there is a chance that they actually each somehow made PS4/XB1 able to play these discs. That would be a pleasant surprise. Believe it or not, 4K TVs are expected to be quite affordable within the next few years or so (Perhaps at a price of sub-$1000). I read that 4K might just become ubiquitous, as in every HDTV would be 4K (and maybe 3D). To me, it seems the prices of these 4K TVs are going to drop much quicker than HDTVs (and 3D HDTVs) ever did. Although 4K might seem like the future, Sharp is currently working on an 8K TV (http://www.pcmag.com/article2/0,2817,2413918,00.asp).
