NikoDoby "720p is the most I'll ever need, really?! I'm biting my tongue because there's just no point, but I guess you also think your Atari 2600 is at the limit of everyone's gaming needs too"
Way to strawman me, NikoDoby.
Please limit your arguments to what I said, not what you wish I said.
For I did not say, anywhere, that 720 was enough for you, I said that depending on viewing range (and screen size) 720p was more than capable of PPD numbers greater than human perception, and that 1080p moreso.
There must be an economic incentive to push new technology to adoption - not just a technological ability. DVD-A and SACD have both failed in the marketplace, despite having superior specs to red-book audio. (Though we at HA are still waiting for a successful 24bit vs 16bit ABX at normal (sub ~130db peak) listening levels.)
So long as video standards are controlled by least-common-denominator (terrestrial broadcast) economics, there just isn't the bandwidth for wide adoption of >1080p. Which is why I mentioned a cultural move towards more large (larger than home theater) display of HD video. Human PPD sensitivities to moving objects are much lower than their PPD sensitivities to static images, and therefore at normal (sane) viewing distances 1080p will _likely_ be judged as "good enough" by the marketplace as a whole for a while to come, regardless of the technological ability to do more.
And if 2 megapixel video frames are good enough for a magazine double-truck I don't want to hear anymore about the D700 only shooting 12MP stills! ;)
