Saw this, thought I'd share:
http://media.ntu.edu.sg/NewsReleases/Pages/newsdetail.aspx?news=863947f9-972d-42d2-947f-3f437f6c3877
A new sensor type that performs exceptionally well in low light situations.

Also, this looks cool too:

Full frame sensor in a retro looking mirrorless body.

There have been many claims for "new sensor types".
The "1000x more sensitive" claim is abject BS. Quantum efficiency of modern silicon-based camera sensors is around 60% (ie 6 out of 10 photons are converted to a measured electrical signal), so the reality is that it's not possible to get a camera even twice as sensitive as current models - there's less than one photographic "stop" left to capture.
If there's a future for new photo-sensitive materials, IMO it's in cost reduction, carving and etching photo sensors (or photo voltaic cells) out of silicon wafer is expensive. And especially when it gets to larger sensors - like the 36x24mm "full-frame" sensor in the Nikon DF.

The Nikon DF is (IMO) a waste of time. 40% more expensive than a Nikon D610, and offering nothing in particular apart from anachronistic retro design - pointless because like other DSLRs it's packed full of modern electronics and user-settings which need to be accessed, plastered with dials "retro style" in order to achieve that, it's a mess. Ergonomics in Nikon DSLRs are generally pretty good, over time they evolved that way for a reason - not specifically to "look cool". General exception to Nikon's good ergonomics is the position of the AFS/AFC/M lever - horrible position due to need to keep backward compatibility with AF and AF-d screw-driven lenses.
I'd hoped that Nikon may have had the guts to do a full-frame mirrorless camera. Sadly not.
The compatibility of the DF with "pre-AI" Nikkors is a bit amusing - back in the early '80s, I had my last remaining pre-AI Nikkors "AI'd" - so they'd work with my Nikon FA and FE bodies. There p[robably are a few non-AI'd (and some cannot be modified) rolling around in people's basements.
One of the promo shots Nikon has released shows the camera alongside a 43-86 zoom Nikkor. As an ex owner of one of those lenses, and while at the time ('70s) it was an interesting lens only because there wasn't much choice in "normal" FL zooms, the 43-86 is really quite horrible, with some gobsmackingly poor distortion characteristics.

Pretty impressive if you ask me.
