New blu-ray out in 2015 with 300GB, followed by 500GB and 1TB discs. Ready for 4k content.
You can get 4k streams. 4k is broadcast in some countries. HDMI 2.0 out for 4k 60fps.
It's developing and expanding.
Didn't realize we are in 2015 and all that has been already purchased by the masses and became the standard globally (at least 10 more years).
This new console generation (lasting about 7 years from now) won't have much content in above 1920x1080 resolution. Heck very few games actually run at that "inferior" resolution, for example no GT games has so far and the latest two with noticeable framerate issues at release date.
Furthermore, I don't think the GT games on the PS4 will even run at 1920x1080 (very far from "4k") at actually stable 60fps, which was supposedly the standard going to be used 10 years ago in console gaming. The jump from the PS3 to the PS4 won't be that high. Those GT games will still be in the the 1440x1080 area with upscaling, which is not 1920x1080 (formerly marketing-wise known as "1080p"), and still running between 50 and 60 all the time.
The mass media numbers and terms will be pretty much the same in the PS4 GT games compared to GT6, with the big improvements in other numbers (textures for example) and mostly on sounds, which should be night and day compared to GT6 because the samples restriction won't be there.
Finally, expect a GT game running (playing in-game) at "4k" at all times and at good framerate in GT9 if not GT10 on the PS5, a time when people will be talking about 8k
Is there really a noticeable difference between 60fps and 120fps? That seems like a waste of resources.
Try 125fps yourself on the pc, hopefully with a pc monitor that does "active" 120hz, no wireless controllers, no motion blur and of course no vsync. The difference is night and day, noticeable by everyone both on visuals (looks smoother) and increased responsiveness (feels better).
Of course the experience is better when fiddling with settings, in some particular games and using particular hardware, but it's fine with what's written.
It's not just numbers and marketing like it happens with "4k" resolution, as resolution itself doesn't matter that much now that the standard is quite high already ("720p"). That's why developers currently don't push to get high numbers just because, as in the end what matters is how the game looks and for that the best way is not to push resolution way too high.
Then again console consumers and 'gamers' in general really shouldn't care about that because it's not going to happen for the masses:
1) Few software supports 125fps. Of course it's in the hundreds of games area, but that's few compared to the dozens of thousands of games out there.
2) Because it isn't the default it gets a bit technical purchasing and configuring. Isn't difficult or anything, but it's an additional process.
3) Running a console game at steady 125fps instead of 60 requires lowering graphics substantially, for various reasons, which is something few would welcome.
4) 125fps is not on demand. The vast portion of 'gamers' are accustomed to 30/60fps with a 60hz monitors and they actually like that. Plus they haven't experienced it.
5) There are other related aspects to truly enjoy the experience which are expensive themselves. Great screens, great inputs, etc. in the end cost more than a console and if newer consoles are going to have games running at that framerate with the graphics we are used to it would necessary mean an increase in cost/price.
So with all that said, for most people's experience with videogames 125fps would be a waste of resources, but on the technical side it is not.
Think of it as the current VR projects, or using a racing wheel or triple screens or having great sound in general: it is objectively much better but just isn't for everyone. The type of thing that once you tried that you just can't go back, willingly at least, that becomes just a niche because of all the listed downsides, an enthusiast type of thing. Main reasons are that 'above standard' anything is more expensive -sometimes considerably more- and a bit more complex.
