As I said on N4G:

Movies? maybe.
Games? No way José. No chance Lance. Never Trevor.

That is not my N4G username.

HDTVs were first introduced in the mid 1990s and became a mainstream product in 2009/2010 ... It wouldn't make sense to support 4K resolution until (probably) nearly 2020, so I would say no

Ultimately, if I was Microsoft I would probably focus on 720p. They could probably produce a healthy bump in visuals by using a GPU like the Radeon 7870m while keeping costs and power consumption (relatively) reasonable as long as they didn't go crazy with trying to push the resolution.

I really doubt it, high end PCs would even have a heart attack running games at that resolution. Unless they are planning on making games look as crusty as NES games I just can't see it running games at the native 4k resolution

I don't think a system being capable of doing 4K is a big deal. At least for movies, but running games at that resolution seems unlikely.

#1 Business, #2 Technology.
The new technology 4K HD is expected to initially be very expensive, so 1080p HD will have to make do for next generation.

Most modern graphics cards support rendering in that resolution so the only question is if MS is going to support HMDI spec 1.4b or even wait for HDMI 2.0. It all depends on a high speed HDMI port that can output 2160p60 and 1080p60 3D. The currently used 1.4a spec is limited to 2160p24 and 1080p24 3D. The rest is all software upgrades.

HDMI 2.0 will probably be revealed at CES in Januari 8-11

The HDMI forum has been meeting over the past months to determine the direction HDMI should go in the future. The two directions put forth included (a) an improved TMDS 6Gbps per lane proposal backed by Silicon Image and almost all of the TV manufacturers and the (b) Micro-Packet proposal led by Apple, Intel, AMD and others to make use of existing Displayport technology. While it was expected to be a close call between the two, the enhanced TMDS 6Gbps approach outperformed the Micro-Packet path. As of this writing, the enhanced TMDS 6Gbps per lane (18Gbps total) will be the protocol for HDMI 2.0.

In addition to the higher data rate, there are expected to be additional features which may include additional 3D functionality, more than 8 channels of audio, CEC standby and wakeup and more.

Keep in mind this is a specification only and there are few current products that could natively meet all of these new specifications anytime soon. In fact, there are still many features in the current HDMI specification that still have yet to be realized by hardware manufacturers to date. As was the case with 1.3 to 1.4, this new specification will serve as a roadmap to future functionality and it will take some time for the manufacturers and technology to catch up in every day use.

The official HDMI 2.0 specification is expected to be released by the end of 2012 with the CTS compliance testing specification expected in February or March 2013. We will of course keep you posted as we learn more details concerning HDMI 2.0.

No, the X720 will only be able to do 720p

The PS4 will probably someday have it for movies....Maybe the Nextbox too.
Probably over streaming and their online library is a great chance too...Sony and M$ will focus more on this in the future so its more a thing with the internet connections of the people.

For games?No chance
They won't make a jump from upscaled 720p/1080p to 4k.
They will see that they can have NATIVE 1080p with 60FPS for all of their games,especially Exclusives.
People always forget or don't understand we have no REAL Games(on quality level of an Uncharted,The Last of Us,God of War,Halo etc) with NATIVE 1080p in this Gen - NATIVE is the important word here.

As someone here said > HD were around long time before it was the current standard.Those HD TVs were exactly as expensive as Ultra HD TVs are now.
In around 10 years they will be 500-1000$ depending on size and features.At the same time we will already hear about new stuff like ULTRA GIGANTO LASER HD or so and afraid people will say "OMG WE DON'T NEED THAT" like they are forced to buy them fro 30k.
But we have that everytime when something is changing.Guess what?Next year maybe Xbox people aka those who think BluRay is crap and not needed will say its the greatest thing ever.Sudden change.
The same happened with HD TVs...The people who still had to play on SD TVs at the beginning of this Gen said HD TVs are unnecessary and only for rich people until they had one.
Its in the human nature to hate the things you can't have/afford.

Or people are getting fed up with the resolution nonsense. And want it to stop. There's a point where it becomes pointless. 8 channels of audio. 7.1 was already ridicules in your house setup. 4k-8k. When you need to be super far away to properly view it. 32 inch TV's are the general public norm. and that doesn't even help out 2k. The constant problem in properly releasing shows on blu-ray. PS4 and XBOX whatever won't do 4k. Next gen will.
