Chasseur d’image knows that the E-P2 should be released before the end of the year and it will have an electronic viewfinder. A japanese website claims to know that the EVF will be external (like the one from Panasonic) and the E-P2 should come all in black.
P.s.: Amazon.com always shows the E-P1 + 17mm lens as NOT in stock….but G.C. today received exactly this combination from amazon.com. So if you want it get it here (Silver Olympus PEN E-P1 with 17mm f/2.8 Lens and Viewfinder). May you will be lucky enough to receive the combo soon.
