Consoles that run Triple A games in 4k won't be seen until 2020 at the earliest. You will likely be playing Hexic 4k in the next year or 2 but that is the best you will see. Even Val's links had at best a 50% saturation base of people with 4k TV's by 2020 and my links had the estimates even further down the road. It was hard enough to push HD onto people and consoles actually helped get those numbers up back then. 4k is a MUCH harder sell than 720p was because many people just don't see a difference unless they have 55" or larger sets and are sitting close enough. In fact, by the time 4k gets a foothold we will already be onto 8k or something.
Resolution is becoming more and more irrelevant. It gets to a point people don't notice or care.
Just like BR vs DVD.
DVDs come around and everyone is buying them like crazy. I think most people out there even have multiple DVD machines. A big jump in visual quality and all the digital perks that a tape cannot give (chapter select, bonus features, closed caption etc...). And that's despite people having PS2 and XB which played DVDs to start with. People still wanted dedicated DVD players.
BR comes out. The res, visuals and audio are better. But where's all the people running out and replacing their DVD machines? Some people have. I got a new BR home theatre set up. But I'm sure many people out there never bothered with a BR player.
Same goes for TVs. People went out and replaced their bog boxy CRT or projection TV with a 720p or 1080i or 1080p tv. Goes hand and hand with digital cable and lats gen game machines.
4k TVs are out and costs are reasonable. 4k TVs are $1,000-2,000 (CDN). Just a matter of time when they hit that $600-800 range. People had no problem spending $1,000+ on HD tvs, but where's all the people replacing them with a 4k $1,000+ TV?
I know nobody who is gabbing about 4k TVs or itching to replace their plasma or LED.
And where's all the 4k content? How much media and TV channels are 4k? There's tons of nicely priced TVs that can handle it, so where's all the media to catch up to the TVs?
