I wonder if the 3D Audio system will include special hardware like the PSVR which changes the sound based on the angle of your head? If so, it could be pretty awesome, as that system is incredible for increasing immersion. If not, then it's really only a minor improvement except to those with acute hearing.

Earlier quoted context omitted.

Resolution isn't an indication of image quality. Just like megapixel chasing in photography. Sure it's 4k, but it's heavily compressed, just like the terrible audio quality you get still to this day. They aren't streaming you 100GB.

have you run 4K video through things like Handbrake? They've been proven to seriously reduce the amount of space (and, therefore, bandwidth) that video files need, and considering that 4K videos have about three times the resolution [1] they have a lot of space to gain from it. I would guess that there are appliances that can run some flavor of compression in real-time to get 4K to stream well. Yes, it will take more…

4K is 3840x2160, or 4 times 1920x1080.

Pedantically, 4K is 4096x2160 but UHD has come to resonate as 4K thanks to TV marketing.

Great to see we're finally getting an SSD by default in consoles. The only thing I'm worried about with this is the fact that high capacity SSDs are more expensive and with a push towards more digital storefronts, I'm wondering how this will work for the users. Then again, it's also a wonderful chance to push streaming, so there is that too.

For a read heavy environment, QLC SSDs should be fine. Sony can probably get the raw QLC flash at something like $.05/GB by next year. They also will have less returns due to damaged consoles, as magnetic HD are by far the most delicate part of the system.

I've always wondered, which is better: a 7.1 system or stereo headphones with "3d audio"? And if 3d audio is so great, why doesn't everyone just use stereo speakers (maybe with a subwoofer)?

Listen to some binaural audio samples with headphones. You can't get that effect with stereo speakers since they're too far away from your ears. https://youtu.be/aQH-jwE_kfo

This doesn't make sense to me. I've used 7.1 and 5.1 systems that have very good stereo imaging, and being able to place sounds clearly on one side or the other like that... didn't seem unusual.

Interesting that while Microsoft and now Google are building platforms that are de-emphasizing local hardware, Sony recognizes this as an opportunity to differentiate by focusing on how great their box is. Their was a passing reference to a "cloud strategy", but there hasn't been as much evidence as their competitors. This will wind up making for the most interesting console generation since the 32/64 bit era, since…

Sony had their cloud gaming phase back on 2012 when they acquired Gaikai for $380m. Not sure what happened with them, maybe it was before its time.

PlayStation Now still exists.

It’s been a long time since I took a class on compression, but I wonder if 4K has worse image quality than 1080P at the same bitrate. Anyone know?

It will depend on a bunch of things (codec used, encoding parameters, size of the screen, etc.), but most likely yes.

8K is such an insane waste of processing power.

I wish they make it run at a stable 60fps instead. You have to have a large screen or sit close to the screen in order to benefit from 4K. I can't imagine how large or close a 8K screen needs to be for any benefit at all.
