Amazon has the silver Olympus E-P1 and 14-42mm kit listed as "Available July 7", but they have already shipped orders to a few lucky Serious Compacts readers who kindly ordered via our product links. I don't have one yet myself but am excited to read your impressions. I do have a Sigma DP2 in hand (courtesy of Sigma) in anticipation of the shootout. Some preliminary impressions coming soon.
