The Japanese "Digital Camera Watch" just posted a review of SIGMA's last addition to its dpX Quattro series using the latest version of FOVEON sensor. The new dp0, which didn't exist in the previous dpX series, boasts its "distortion-free" 14mm/f4.0 lens for its APS-C size sensor.

Here's the link to the article:
