The ps4 will mostly have the ability to hook it up to a 4k-tv. Internally rendering AAA-games at 4k is way off for the ps4 unless sony will sell it for an expensive price which will most likely not happen. done.

why not? its not really impossible, and In less than 4 years LED tvs took off.

No it is 24 gamecubes taped together.

So your telling us that PS4 wont be truly viable until its at least 3-4 years old

Sony is pushing the new Bravia 4k resolution and the PS4 will support this resolution for sure...

 4k is 2160p = 2x 1080p (4x more pixels)

The actual GPU series from AMD and nVIDIA support 4k resolution.

People complain about 3D adoption rates yet somehow expect a technical extravagence to take off when companies will be charging a huge premium. 4k will be stillborn, it has zero chance at success without more native sources to take advantage. Its simply a decade too early for the vast majority of consumers (above 99% if I had to guess).

Still impressive as a tech demo, I just don't see the point of pushing the tech...

again - what means "support" in this case? that you can hook up your gpu/console to a 4k-tv. nothing more and nothing less. this has nothing to do with the quality of the images/games that are to put out through the interface. the tv will upscale no matter what internel res was used by the gpu.

Sony shouldn't push for 4k all it will do for them is drive up costs to own a PS4.

I don't know, but why not?

Well itll drive up costs in the early adoption stage, and could alienate most buyers in the first few years. Most people still have Plasma/LCDs, only recently been buying LEDs. You need a console that you can utilize day 1 or else the road to that viability will be rough.
