Shopper a few months back:

Currently the only camera to use an
X3 sensor is the Sigma SD10 which, at around £1000, is best considered a
professional's camera."

This shows little more than the author's ignorance of camera technology.
The Sigmas are right at the bottom of any list of DSLRs because of poor
image quality and the proprietary lens mount. They don't even make the
grade as "amateur" cameras. Nikon and Canon both announced new top-end
DSLRs, using Bayer filtered sensors, because these still produce
superior results.
