I'm just excited that it has an "oversized" sensor, like the LX-3 did. When you change aspect ratios, it doesn't just crop from one of the other aspect ratios; it actually changes both dimensions and uses all of the image circle. I think that makes it the first interchangable lens digital camera that shoots 1:1 and 16:9 natively. I'd love to see that thrown into a stripped-down, stills-only, smaller body without a "prism" hump.
