This seems a common DC, but dpreview tells that this one has a wider dynamic range than normal DCs, “(i)t helps to suppress white-out and expands dynamic range by up to 1EV compared to previous models.”  And they also pointed out that the technology Ricoh uses “is in contrast to many existing dynamic range expansion technologies that limit the available ISO range (and can result in increased noise), or reduce the camera’s performance when engaged.”  And they further note that “(f)or more extreme lighting situations, there is also a built-in high-dynamic range mode. This shoots two, differently exposed, images consecutively and combines them to enable to capture of a greater dynamic range than would be possible in a single exposure.”

Finally, Ricoh “claims the CX1 will be able to capture and convey dynamic range of up to 12EV. However, Rioch stresses that its feature isn’t trying to produce the fashionable, heavily-processed ‘HDR-look.’ ‘it aims to portray the scene in as natural a way as possible.’”

This sounds very interesting, I look forward to seeing the samples made buy CX1.
