Anyone have any more info on this camera and or technology?

The Lytro Light Field Camera boasts an 8X optical zoom lens with a constant f/2 aperture, capturing maximum light across the entire zoom range.

Light Field Resolution = 11 Megarays the number of light rays captured by the light field sensor.
Don't even know what to make of that, but it sounds very interesting.
Interesting/revolutionary concept for sure but the price point appears too steep. Even with the few hurdles at the moment, I'm not sure if a constant (and only?) f/2 aperture would also work as the DOF will limit its application to something more toy like.
You're not likely to find a better source of information about the camera and the technology behind it anywhere else than on their own website. The technology is discussed in great detail in the inventor's PhD thesis, here. https://www.lytro.com/renng-thesis.pdf
My own take is that it's an interesting technology, but it's years away from being widely implemented. Note that the company has been around since 2006 and this newly announced first product is really just an expensive toy that demos the technology. And it's not like you can't capture a scene in the depth of field domain today, because you can using focus stacking. Take a series of photographs focusing at a variety of different depths, and then at a later point in time you can choose the image that has the focus where you want it. Alternatively, you could blend the focused areas from selected images in the stack to extend the depth of field as deep as you want. The Lyto technology essentially streamlines that process by capturing all that information in the same frame.
Of course you pay a high price in terms of storage requirements to do this. Note that Lyto doesn't even give a comparative sensor resolution in pixels. Most competent photographers are already experts at controlling focus, so they're not about to trade-off image size, image quality, and capture speed for the ability to focus after the fact. They're going to get it right the first time. Now if you didn't have to compromise on other areas to gain this feature in future cameras, then sure. It would be a great feature to have. But that's clearly not the case otherwise they would not have released a version of the camera that is so grossly limited at a very high price point. On the other hand it will be an interesting technology to watch as it matures and makes its way into future camera designs.
Even with the few hurdles at the moment, I'm not sure if a constant (and only?) f/2 aperture would also work as the DOF will limit its application to something more toy like.
That's not a problem as their software is capable of extending the depth of field to anything you want over the entire focusable range of the camera.

That will make it even more interesting. From the little I got with playing around is that the DOF is rather limited to area we choose to focus. May be the software will offer greater flexibility.
The quality of the photos is disgusting. I wouldn't think twice about it at all. Best you save that $500 bucks and buy a new lens for your dSLR instead.
