I read this very often and I am still surprised that there are countries where internet-traffic is limited - in Germany this only happens to mobile-internet. Internet via copper or cable is generally unlimited per month.

A fucking useless waste of money as it is now. Let somebody else pioneer it, then steal the ideas and make it better, like all other successful companies, Sony.

Data Limits aren't really the issue, though. The biggest obstacle is bandwidth limits. I am often terrorised via my letterbox by shiny bits of paper which promise me (up to) 60Mbits of interbutt, but these promises rarely deliver, and I have experienced much arse-sitting after a certain time of the evening, or after a certain allocation each day (I don't fuckin kno), whereupon my bandwidth slows to a crawl.

NOBODY EVER GETS THEIR PROMISED MEGABUTTS, but the weasely language lets the ISP off, since "up to" includes anything between that and fuck-all.

Plus, there is the whole issue of infrastructure. There are far more flaky things to rely on than copper / fibre / bandwidth caps - how will the data be distributed? the availability, nay, hackability, of Servers and Nodes creates another obstacle.

Guys, even I don't have a fast enough internet to stream 4k according to these 100GB plus numbers.

This is defiantly many years away.

I wanna steal ur internet!

Agreed. This is a future proofing feature not a realistic bullet point for launch.

Well, "up to" is almost always exclusive to copper-based connections and these are also set to get worse over time but yes, that's really an issue. With cable, yes shared medium (as every ;)) but at least in Germany you get what you pay for. But that's of course only "your" side which can also reduce your bandwidth - imagine which devices we have at home, nowadays. I have 3 computers, TV, Bluray-player, x360, Nexus 7 and a smartphone and all have access to internet (of course not everything is powered on parallel ;)).

To add to "your" side is your ISP which has to have good peering-partners which cost a lot of money but I don't think that's a problem nowadays. 

The other part is the content-provider, say Sony, MS, Gaikai, Nintendo or whatever. They use content-delivery-networks like Akamai to ensure that data you demand gets streamed to you from the nearest possible server residing in the nearest possible data-centre via the best possible network but somehow I feel the quality of these CDNs highly depends on what you pay for example Akamai. Look at Apple - when they release a new ios-softeware millions of users get it and receive it at decent speeds. Seems to work with Akamai. And then we had Nintendo last Christmas and the sad story of the first WiiU-update - but Nintendo is using Akamai, too! So I think Apple pays a lot more than Nintendo ;)

And given all this I am by now not very confident on what Sony will deliver with Gaikai. There are many traps that can ruin your gaming-experience....

Somehow I can't believe that pic as ist says 0ms ping...

But here is mine :D :

Will the PS4 come with a BDXL drive. Once that will play triple-layer and quad-layer Blurays?

We can forget streaming 4K movies.....we can barely stream 1080p!"

I'm thinking that too, and even sooner.  I don't have the fastest connection in town, but I can stream 1080P, and someone in another room can stream 720p, and it works fine.  Plus, the new standard will make it even more efficient.  (I am assuming both the X720 and PS4 will include the .h265 standard.)

There were so few 720p TV's when the Xbox 360 came out.  But now, everyone is 1080P (well, where I am).

I think at over 40" 1080P just doesn't cut it.  (I have a 52" TV, and like it much, but yea, the resolution could be better.)

I could see 6' and 8' 4K TV being much of the standard living room TV of the future in a few years. 

But, just like the PS3 pushed out Blu-ray.  I think they will use PS4 to push their 4K TV's.
