It may be technically amazing, but it's likely you wont be able to see the difference. 4K has a far lower chance of success than 3-D TV. At least with 3-D TV, you're able to see a difference. The only buyers of this technology will be the 1%'rs that want and can afford a full room wall-sized display like movie theaters have. This is not a big enough market to make it worthwhile.
i agree with the 1st part of your statement but not the 2nd part. higher resolution is only a matter of time even if it's just another marketing gimmick. people are now offered 3d in their tvs for no further cost. whether they choose to put on the glasses and seek out 3d content is up to them. if you offer 4k to viewers for no additional cost, they won't need to do anything to reap the benefits. it uprezzes 1080p nicely and doesn't require annoying glasses.
