It's in here: http://www.pentaxslr.com/images/SHAKE_REDUCTION_FACT%20SHEET.pdf If you have three sensors, and they have, the difference between two sensors with the same orientation but positioned on opposite sides of the frame they will be able to measure rotation. It is not very clear from the document, but at least it is possible and I know this has been mentioned other places as well.
