I expect it to be much like 1080p on the PS3 now. Used just for movies. At best some lower end games like Disgaea, 2D fighters and simplistic PSN games with easier to render art styles like Sound Shapes will use it. Other than that, it will just be for movies.

I say go for it Sony, make another powerhouse.

no I'm not...like I said before what I was saying was in a joking matter containing to everyone speculating and making them seem like they know better than Sony. regardinf to pzeus's post. You can speculate all you want, hell you can say "Sony's creating 4k resolution to turn all it's buyers to mindless zombires to overthrow the major governments of the world"

frankly I don't know where this is going, not that you don't have to right to quote me but my quote was directed to pzeus in how this tread was getting a little out of hand.

At best?  While very few games on "BOTH" the 360 and PS3 run at native 1080p resolultion, it's not "just simplistic games" that are 1080p.

Wipeout HD, Gran Turismo 5, Sacred 2, and Ninja Gaiden Sigma 1 and 2.  Like I said there aren't too many, but here are a few games that are native 1080p resolution rather than upscaled.

Unless they're PC gamers, one thing you might hear people saying is that you can't tell the difference between 720p and 1080p and unless it's side by side and you take the time to look back and forth, usually you can't.  It's not too big of a difference.  But let's say you were running 720p and 1440p.  The difference would be very noticeable and not for the reason that a lot of people think.

Higher resolution is like starting at a picture zoomed into 200% and then zooming out to 150% or 100%.  There's less blur on the picture and you have a larger viewing space.  It can also just have more pixels added onto the same picture to look more defined without increasing the viewing space.  

Here's an example of going from a lower resolution to a high resolution picture.

 4 times as many actually.

HappySqurriel beat me to it...

HDTVs were first sold in stores in 1998.  Were the Dreamcast, PS2, Gamecube or Xbox based around HD?  Even when the 360 launched in 2005, most households didn't have HDTVs yet.  It's going to be 2020 at the earliest before we see adoption rates from the masses regarding 4K TVs.

People need to understand that the entire industry has just spent millions upon millions upgrading the infrastructure for 1080p; Blu-ray, network/cable channels, etc.  There's no way the industry is suddenly going to do that again and upgrade in the next few years to support 1% - 2% of households that buy $20,000 TVs.

As far as movie watching, I can't imagine that a 1920x1080 blu-ray will look significantly better upscaled to 4K resolution on a 65" TV.  Upscaling is nothing more than filling in all of the extra pixels with "false" picture information based on the existing real ones.  This is why a DVD upscaled to 1080p doesn't look nearly as good as a Blu-ray, which fills all 2m pixels with "real" picture information.  For 4K, we're talking going from 2m+ pixels to 7m+ for digital cinema 4K... that's over double the amount of pixels being filled with "false" picture information, which could result in heavy amounts of visual artifacting.  It would take a native 4K disc to really take advantage of a 4K display... and again, the adoption rate just won't be there to justify this for many years.

To the point of Sony's decision to include 4K with the PS4, well, I guess it just depends on how much extra it's costing them to do so.  If it's very, very little, then there's no harm in including it, I suppose.  But unless Sony plans on delaying the PS4 until 2018 or later, the vast majority will not embrace its advantages.

There are some exceptions that I forgot about, i'll admit. For the most part it 1080p native is very rare on the retail releases though.

ps3 already supports native 4k....

for viewing pictures that is, they had a patch for that a while ago.
you can view 4k photos.

i have no clue, but whouldnt that mean Gt5 is in 4k. or would it upscale or something?

Honestly isn't the only way to have 4k resolution would be to won a retardly large tv? I mean even bigger than a 40 inch I say.
