By “generation,” I mean sometime in the next 15 years or so.
I’m guessing 1080p isn’t the theoretical limit in television picture quality, but bandwidth constraints may make it the short-term practical limit. That said, progress marches on, prompting the question: Have researchers hinted of any work toward even higher levels of resolution?
I’m saving up to buy a 1080p television in three or four months. So 10,800p should be ready sometime around March.
hopefully in 15 years time we’ll have direct retina displays that shine light right onto the surface of the retina. Then we can get decent fields of view
It’s actually an industrial secret, but we’re just waiting for your card to clear before we announce the 10,800 p. Funny thing its that we expect it to be significantly cheaper, as well as both lighter and larger, while still managing to consume less electricity. There’s a huge number of people waiting for this, so please buy the current model, preferably on a non-fundable basis, as soon as possible. 
Seriously, though, much more advanced display technology is already out there in industrial projectors, which lead the market.
This baby is 4096 X 2160, allowing for four full HD signals (1920 X 1080) to be displayed simultaneously. Downside is that the SRX-R105 model, with “only” 5,000 ansi lumens has a price of $65k. The 10k ansi lumen model is more expensive, of course.
We will see devices with greater resolution for the home in “a number of” years. The $64,000 question is how long is “a number of”. I wouldn’t hold your breath or put off purchasing a new unit. I just bought the 37" Panasonic HD plasma. Really beautiful and cheap! About $2,000. I’m going to add an 80" screen and a projector as well. Japan broadcasts in high def, and it looks so much better, I may start to actually watch tv again.
There are a few problems with getting higher resolution units into your home. First, the cost, but things will eventually come down, as they have with high def units. Second, is source material. Computers now have higher resolutions, but DVDs converted to film are not being done at higher resolutions. Broadcast resolutions are another factor, as well as all the peripheral equipment, but if the prices can come down on these super high end projectors, they will cause a ripple effect so you can eventually watch mindless reality shows with far more beauty than the plots.
In the meantime, enjoy the current models.
