If one of the OP's is correct and this 46MP sensor is a Foveon sensor, this is similar from what I understand is in Sigma DP MERRILL point and shoot that has a few good reviews. However if it was this simple and that great, wouldn't this already be a trend by now?
Last year I met a photographer who actually had done extensive research on this Foveon sensor and his advise to me then was to 'give them some time to perfect it'. He was shooting a Canon 5D2 and had numerous Sigma and Canon lenses but advised me to stay clear of that technology for now.
