No, I doubt anyone here (other than Jan) could confirm or deny that. But it wouldn't surprise me to find out about shared components. The XL1 used a Panasonic CCD block, the Sony VX1000 used a Canon lens, and I'm sure there are many more examples of that kind of thing going on. The interactions and interrelations and cooperation of Japanese companies seems bizarre to westerners but is quite common over there. Even though Panasonic and Sony are bitter rivals, they're also partners in AVCHD. Stranger things have happened.
Thanks Jan, funny I was just talking to you at an expo about that. I was actually curious more about the actual specs being very much the same versus who made the products. I should have been more specific. I was more wondering if there was opinions out there on the two sensors and which they like. It's tough to choose between two cameras when the have basically the same features, same sensor and price point.
