I was going to post a separate thread about Olympus but might as well jump into this one.

I've been happily clicking along with my E-520 as well and haven't spent much time keeping up with the latest equipment and trends. I've had the camera for a few years and am pretty happy with it but recently started thinking about upgrading or augmenting my lenses. I was very surprised to see that Olympus now only offers one 4/3 camera and seems to only be concentrating on the micro 4/3 line.

I'm not quite sure what to do myself at this point. Does anyone think they will ever release a more modest priced body, something along the lines of the E-620? I'm not unhappy with my gear but the E-520 does have some shortcomings under low light conditions (noisy above ISO 400, slow auto focus). I've certainly learned to deal with these issues, but it's somewhat disheartening to know that the only upgrade is a $1600 body. I've had my eye on on a couple of lenses, but I'd hate to think that they'll be obsolete in a couple of years or that if something happens to my body I'll have to upgrade to a more expensive one than can afford.

Should I be looking at the micro 4/3 line? My understanding is that you can adapt the 4/3 lenses to the micro body but there are some drawbacks, especially with auto focus. Would any of the micro 4/3 cameras out now be considered an upgrade to the E-520?
