SonyRumors reports that Sony has updated PlayMemories Studio to version 2.0 for the PlayStation 3 which adds 4K image support and 720p photo and video archiving. Its believed that the PS4 will include native 4K playback and this is merely a preparation for the next generation console.
You really hate Nintendo don't you.
On topic. It's nice, but not revolutionary. Basically it allows your PS3 to playback the photos of your 10+ megapixel camera.
One thing that intriges me is why it's easier to capture 4k photos, than it is to view them. I'll have to research that.
But 4K games aren't coming to console anytime soon. If anything we'll probably get a Super Stardust 4k, and that's it. As others said there 1 no need, because 4k isn't really helpful unless you have a 80"+ HDTV, and with a TV that size it's going to be in the $5,000+ range for a while.
Sony set a goal of 1080p @ 60fps in 3D for a reason. Even a high-end (well High-low) GPU like the 7950 struggles with PC gaming in 2k @ 30fps with the most graphically intensive games, so 4k is out of the question.
4k is only possible if Sony and MS do 4k remakes of their current-gen games (as far as retail games go), and even then that's unlikely without a powerhouse GPU to run them.
Not 2k @ 30fps.
Everything else applies
OK for short..
4K will one day become common just like 1080p. The only question is how long will that take.
