For those who might be interested (and who haven't seen these elsewhere), here are the JPEGs released by Olympus of what they're calling the "concept" camera...presumably the current state of the prototype mock-up for the coming top-of-the-line or "E-2" body. (These pictures are currently available on the Oympus press site under Consumer Products > Product Images > Digital Cameras > E-System Body > Concept Camera. No newer pictures are currently on the site.)
PhotographyBlog has also published some pictures of the "P-1" mock-up shown at PMA.
