I'm lusting after this camera.
I owned an E-1 and used it daily for work for two years. I absolutely loved it. I only switched to the Canon when work switched. And, actually, just picked up another E-1 for myself - small, light, weather sealed and now, cheap ($500) The Olympus have an image quality that can't be explained, it is just beautiful.
The E-1 falls down a bit at high ISO, something the E-3 has drastically improved upon. But if the E-3 is anything nearly as good, reliable and ergonomically pleasing as the E-1 this will be a winner (and all reports I've been reading, no obsessing on, make me think the E-3 is a worthy successor).
Olympus glass (the high end stuff) is, in my opinion, among the best in the industry as well. (I've used both film and digital cameras from Oly professionally at various times ... along with Nikon, Canon, Leica and Contax so I have a bit to compare it to).
