is the hpx 500 really a hd camera ?

I've been closely looking at the xdcamex in comparison to the hpx500, I think I've read every post on both cameras however the sticking point for me is the sd chips in the 500. Sure the 500 records in dvcprohd but if the camera head is sd can it really be classified as a hd camera. Are there any resolution charts that indicate the 500 can resolve that much detail ? I don't really care about the pixel shift technology, for me if it works and the camera can capture the same detail as the xdcamex can with its 1920 x 1080 sensors then great I'll get one.

Are there any comparisons on line regarding these two cameras ? As I have spent my career working with 2/3 inch shoulder mount cameras my preference is for the hpx 500 however I just need to be sure that the image the camera records is in fact hd. I can't even find any information on the native resolution of this camera. I think the xdcamex is 2 million pixels ?

Thanks in advance for any input
