For obtaining higher resolutions, one needs very high MP sensors, ones that aren't used in commercial quantities yet (100 MP+).

Am not so enthusiastic about the potential for fine photography with the lightfield camera either.
For example, by the time we have those 100 megapixel+ sensors, the performance of the sensors and electronics and focusing gadgets and ultrasonic motors will be so high that there will be other ways of real fast focus stacking. To derive images with some of the features of the lightfield camera. Movies made up out of lots of images taken while racking the focus of a regular lens, for example. Not exactly what the lightfield camera does, but a way in software with fast hardware to give you a little movie that you can click through to get to various images taken at various sharp-focus planes.
And the great thing about the focus-stacking is that it will happen with equipment that will of course still be perfectly usable to take ordinary, superb 100 megapixel pictures. 100 megapixel pictures naturally will have super high ISO potential because you can, say, downsample them 16X to 6 megapixels, with a quarter of the noise.
Having said this can see "potential" for lightfield cameras in some industrial imaging, and low-end point and shoot applications. Or maybe not, because if there's some need for what the lightfield does, regular camera makers once again could hustle up with their own focus racking technology.
