4k is NOT hd blown up to 400%, It's hd blown up to 200%. Twice the vertical and horizontal resolution. People get this confused because you can fit 4 hd panels in 1 4k frame, so they equate these two, but 400%would be 8k
4K TVs now on display at Best Buy…viewers were fascinated but...

Well at least as far as theatrical projection is concerned, a 2k movie looks significantly better on a 4k projector than a 2k projector. How good a scaled image looks really depends on the quality of the scaler.
But we are headed toward a world of scalable video codecs for network based digital distribution where a single file encoded at the highest resolution will be downscaled by the server automatically to match the viewing device and available delivery bandwidth over AVB protocol network switches. We are already deploying BYOD video telepresence systems that do this for multi-point web conferencing over anything from a smart phone to a tablet device to a 1080p/60 distance learning theater.

Most who have seen upscaled BR vs. native 4K seem to agree that it's looks similar. I've always thought 2k scans looks soft in cinema, so looking forward to a shift there. Also we hopefully see some decline in VFX and more models/props/animatronics coming back due to the quite-so-revealing resolution.
Personally I'm highly interested in good RAW 1080p that can be future proofed with scaling.

You always want to start with the cleanest sharpest image possible, and then you can manipulate that image in post for the best artistic presentation in a narrative. Ultra sharp ultra resolution is not necessarily the most pleasing image for a movie, depending of course on the subject matter. I see delicate talented softening of 4k images in post to make them more pleasing to the viewer as the most likely solution. Ultra sharp clean 4k would be more suited for documentaries or medical and industrial presentations, etc. where you want to see the tiniest details.

Now that 4k is around the corner and with more 4k raw cameras and TVs , I predict we will talk alot about softening algorythms in the future on this board. Most famous DPs already using all sort of "in/on camera softing", even on cameras like an Alexa or RED.
Here's older thread of Scarlet users talking about which diffusion filters to use to break up the sharp look of the Red cameras:

And don't forget people used to soften 35mm film all the time. Diffusion filters have been around since before digital cameras because people found a softer image more pleasing.

Had to chuckle at this I must say. How many have said HD/2k is not good enough. Too soft they say. So some spend about 20 k on a new sharper camera just to make it soft again. Pfffffffff. I got lost somewhere in the irony.

Big difference in there though. Spacial resolution is something a super sharp 1080p or 2K camera can't give as well. So a slightly softened 4K image will have tremendous resolution packed in there. It's not exactly the same...though I get the irony you speak of
Resolution doesn't have to equal sharpness...look at film.It has to hit the Goldilocks spot, not to soft, not to sharp, but jusssssssssssssssssst right!

4k is making it's way into all kinds of places.

I believe YouTube supports 4k.
Getting online video onto a TV is rudimentary these days. If the TV doesn't have networking capabilities built it there are a slew of devices that can remedy the situation (everything from video game consoles to blu-ray players to set top devices like AppleTV, Roku and Chromecast).

Some people are happy to view 240p youtube videos but there are many 4K videos on youtube and as soon as HDMI 2.0 comes out along with low cost 4K HDTVs there will be many more people watching 4K.

Correct txdp. Sorry about that. I should have realize that it's HD blown up 200%. I stand corrected.

Kinda wish 4K TVs won't come out, just less expensive 4K cameras. Would be nice to have the room to crop or create a nice crisp 1080p image starting with a 4K native. Even if that camera shoots in compressed H.265.
I wonder if that will be the route to go for several years. Shoot in 4K, compress down to a nice 1080p and then scale back up to 4K when needed. You know it will take years before most people have 4K monitors anyway.

Well ODEMAX beta (http://www.odemax.com/) is finally up and operational. So true 4K content is actually available if you have a RedRay
Pretty soon Sony will have their 4K player as well, supposedly October i think? Question is how long will it take to build up the library of distributed 4K content.

The move to digital made sense to consumers. It was a big leap in convenience and form factors for their TVs. Same is true of the leap to DVD. It wasn't just about quality but the convenience and form factor that made it attractive.
Both Blu-ray and 4k are considered minor upgrades to consumers about they gain nothing but extra pixels. Pixels don't make something immediately look better. It just looks like it has more pixels and detail. I have worked with a lot of 4K material from RED and it is nice but it just will never have the same wow factor for consumers and the massive leap into the digital world.
Manufacturers are struggling to find that next wow factor that will make everybody dump their current TVs, movie players and movie collections but it just isn't happenning. 3D was supposed to be that new wow factor and it was a bust. Now the push is 4k to try to get people buying stuff again.
The move to digital was so good most people now have some form of digital TV and entertainment in their home. Either DVD or Blu-ray or just an online alternative like Netflix. With the market saturated it is hard for manufacturers to sell us new stuff and they are hurting.
While 4k is not bad at all and can be a good thing someday it is too early for the move and it will fail miserably. There is just no wow factor or got to have it feeling and it means consumers have to invest in all new content and devices. Content will drive this and having a cool funky 4k TV and Best Buy is no different than a cool funky 3D TV at Best Buy that everybody crowds around to match but nobody ever buys.
