X20 in stock, Amazon US
Having had mine (also ordered from Amazon, but that scarcely matters) since Friday, I've got to say I wish I'd put the money toward a D-7100 and waited on the X20 until a generation or two of firmware fixes had happened. Pictures are okay, but the operation is different from the X10 in some important ways and not better, at least for certain ways of shooting. I expect Fuji to get it sorted, but would rather be shooting something else until then. May actually rebox the X20 and continue with the X10, awaiting new firmware.
