I'd imagine it'd be too costly for devs/publishers to produce games for the 5k and 10k, unless if the consumers are willing to pay like $100 a piece for a game.
I'm not sure where you guys found the names "5k" and "10k." From what I understand, there exist both 4K resolution (2160p) and 8K resolution (4320p), both of which are currently in development. 4K resolution has 4x as many pixels as 1080p, and 8K has 16x. There were rumors that the PS4 would support 4K gaming, though apparently only 4K video
will be supported. 4K technology does exist already, and 4K video is nothing new; search YouTube for some 4K resolution video (though what you'll see will be only as many pixels as your display will allow). 4K televisions are due to be on sale some time within the next year while 8K televisions are a few years away still. Sharp managed to demo the first 8K TV at 2012 Consumer Electronics Show and broadcasters in South Korea and the United Kingdom have been experimenting with it, so they aren't that far off, in my opinion.
While 4K and 8K video will certainly display much, much sharper images than 1080p, the ultimate goal is to increase the desired size of televisions with this technology. To achieve the optimum effect of these TVs, manufacturers are expecting sizes of 60'' and above for 4K and 8K resolution screens. Since the quality of images will be so high, the only way to make use of it is to increase the size of the display. As we know with current technology, the larger the TV, the more expanded the pixels and the lower the quality; that's why giant TVs (i.e. 90'') aren't all that great to have right now. Producers want to preserve as much quality as possible on large screens, and this is their way to do it. They want 80'' 4K TVs to be as sharp as 32'' 1080p TVs (if not sharper), and 8K TVs to be even sharper. It's soon going to be the age of the large TV.
It doesn't look like the PS4 will support 4K at the moment. It's entirely possible in a few years, though, depending on if Sony can achieve this through a firmware update. I think demand for 4K content will increase once enough consumers purchase 4K TVs. 8K, however, isn't going to be ready until at least 6-8 years from now, which I think would be around the time of the next generation of consoles.
