Very curious what the final output resolution will be. Sure it is fun to be able to not have to deal with focusing until you are back home "developing" the images, but if the final output is 3mp, after you develop you are still left with an image too low-resolution for anything but screen display. In the words of Brian Peterson (Understanding Exposure) for any particular scene there may be many "correct" exposures, but only one creatively interesting exposure. Likewise, in their image gallery there is generally a single focus point that makes the most creatively interesting image, so after you've chosen that point at home, you are still looking at a very low-res image.
Of course, for shooting in the wild, some of their shots would just never ever get taken correctly by an autofocus system and would disappear before even a pro managed to manually focus. And many of us never print a single photo today, so being stuck with a beautiful 3mp image may be enough. They have a stunning image in the gallery of a woman standing outside of a shop, taken through the shop glass. https://www.lytro.com/living-pictures/152 Imagine if she was walking by, not just posing. You would never have time to capture it if you were using a traditional camera.
