The E-520: http://www.olympusamerica.com/cpg_secti ... oduct=1386 The new 9-18 Zuiko F/4-5.6: http://www.olympusamerica.com/oai_Headl ... ressNo=589 I think the lens is more important, as it bridges a gap in the existing lineup for Olympus. Previously you could go as wide as either 14mm OR 22mm, nothing in between. This one is equiv. to a 18-36mm lens, i.e the Tokina 12-24 on a Nikon/Sony APS-C. And it's almost 1/3 the price of the existing Olympus 14mm equiv lens (7-14mm f/4) (price according to their press release). Sigma offers a 10-20mm lens at basically the same price, but that would be a 20-40mm lens. And I think that lens is still waiting to be actually released to the public.
This looks really interesting. I'm holding out for the E-3, although I am really happy with the E-510 that I have.
Update: Got the E-3 and a Zuiko 12-60, but have been to sick to take it out yet...boo... Soon, maybe... I will say that the camera has a wonderful erogonomic feel and an intuitive control layout that I can already tell I will like a lot. Still have the E-510 and still love it. Sold the E-500 and the 2 kit lenses.
